Programming Life: Inquiry & Engineering Through
Synthetic Biology
The report of the first chimeric DNA molecule in 1968 (1) ushered in a new age for experimental biology and biotechnology. The
ability to propagate DNA obtained, in principle, from virtually any organism within the cytoplasm of Escherichia coli (2) set the stage for
sequencing of genes and genomes. This advance enabled researchers not only to connect a mutant phenotype with the corresponding
genotype, but also paved the way for the industrial production of medically important proteins such as insulin. The in vitro construction
of recombinant DNA thus became a cornerstone method in the functional and biochemical characterization of genes and proteins.
The five decades following the birth of molecular cloning have witnessed an incredible scaling-up of molecular biology due, in large
part, to the development of high-throughput technologies in nucleic acid sequencing and macromolecular analysis. But long absent from
the resulting explosion of information has been the ability to rationally recreate, in the laboratory, the regulatory complexity of the very
gene networks forming the basis cellular behavior. In short, we know a great deal about the “code of life” but are only now beginning
to be able to program with it. This aspiration has, in part, given birth to the rapidly developing field of synthetic biology, which aims to
unite the rigor of engineering with the design and construction of recombinant nucleic acids, with which to study and understand the
behavior of genetic circuits as well as utilize them for technological ends.

What is Synthetic Biology?
Though a comprehensive definition of synthetic
biology is elusive, one may characterize it as a
“build to understand” approach to biology (3). A
quote by the famous theoretical physicist Richard
Feynman epitomizes a theme characteristic of the
field – “What I cannot create, I do not understand.” How does this sentiment relate to recombinant DNA? Imagine beginning with a repertoire
of well-characterized DNA “parts” encoding
biological functions such as receptors, promoters,
activators, repressors, terminators and reporter
genes (or other outputs) – and attempting to rearrange them into configurations designed to direct
a biological system (typically, a cellular “chassis”)
to accomplish a desired task. Think a pollution
detecting E. coli cell that expresses green fluorescent protein (GFP) in the presence of arsenic and
then self-destructs after a given period of time, or
an engineered implantable human cell line that
undergoes a preset number of cell divisions and
then secretes insulin at precisely regulated levels
in response to extracellular glucose concentrations.
Such re-purposed cells would be described, in
synthetic biology parlance, as “genetic devices.”
These devices are designed for multi-step behaviors, and relative to earlier examples of genetic
engineering, their design is necessarily complex.
How cells can be programmed for such functions
is neither intuitive nor obvious. Here, synthetic
biology has made a radical departure from previous forms of genetic engineering by borrowing
engineering concepts from control theory and
digital computing as a framework upon which to
design genetic circuits for programming cellular
behaviors. A genetic implementation of one such
“simple” computational operation, the Boolean

Synthetic biology draws some of its inspiration from the engineering disciplines of control theory and digital circuit-design. In
the illustrated example (A), an assemblage of biological components ideally functions to convert two chemical inputs (IPTG
and arabinose) into an output: the expression of the fluorescent reporter protein GFP. Two promoters (PBAD and Plac are each
constitutively repressed until induced by their cognate chemical signals (arabinose and IPTG, respectively). Each operon
expresses half of a two-part transcriptional activator (the SicA and InvF gene products) which together activate the transcription
of the GFP under the control of PsicA. Expression of the reporter only occurs in the presence of both inputs. The DNA circuit can be
represented abstractly as a logic gate implementing the Boolean “AND” operation and is shown with the associated truth table (B).
Higher order circuits (C) can be created by combinations of modular genetic gates; in this example, three AND gates convert four
inputs into a single output. Figure content adapted from Brophy and Voigt (2014).
AND gate, is shown in Figure 1. Higher order
combinations of multiple kinds of genetically
encoded Boolean operations, and other types of
synthetic gene circuits, have been constructed to
perform a variety of simple computational tasks,
including edge-detection, cell to cell communication, and counting of signal inputs (4).
Going from a circuit schematic to a working
genetic device is guided by an engineering paradigm: the design-build-test cycle (Figure 2, p. 4).
A key tool in this process is computer-aided mathematical modeling. Unlike their electrical counterparts, genetic circuits operate under conditions
that dominate the cellular environment. A model
attempting to describe and predict the behavior
of a genetic device must accurately incorporate
a range of parameters such as diffusion, binding
equilibria, networks of protein/DNA interactions,
and dynamic reactant concentrations; a variety of
deterministic and stochastic approaches have been
employed to accomplish this goal (5). As such, the

model embodies a sophisticated hypothesis about
how the device might work. The genetic device
is prototyped (e.g., synthetic DNA is assembled
and transformed into the cell) and its behavior
evaluated in terms of the model. What is learned
during each stage is used to improve the performance of the device in subsequent rounds of the
cycle – through changes to the device itself, as
well as through refinements to the model.
While synthetic biology shares many of the tools
and reagents with hypothesis-driven experimental
biology and molecular biology, it follows a fundamentally different approach. Many of the techniques in a molecular biologist’s repository (e.g.,
oligo synthesis, genome editing) may not exist in
their current form were it not for synthetic biology. Conversely, synthetic biologists can build
upon discoveries made by molecular biologists.
In essence, synthetic biologists assemble genetic components in order to execute an “artificial” function, and in
the process of getting it to work, the engineered genetic
construct becomes itself an object of study and yields
basic principles for application to subsequent designs.
Chemical engineering in vivo
A practical definition of synthetic biology must
also include the latest developments in industrial
fermentation and metabolic engineering. Even a
cursory survey of papers and journals covering
synthetic biology shows a significant number
of reports describing synthetic biology to synthesize fuels, chemicals and materials. Historically, this technology began as an outgrowth of
beer and wine making, after it was discovered
that fermentation could also be used to produce
economically valuable solvents and organic
acids (6). With the advent of greatly expanded
sequence databases, inexpensive DNA synthesis,
and genome engineering methods, it has become
increasingly practical to do chemical synthesis
in vivo. Designer metabolic pathways utilizing
genes encoding enzymes derived from any of the
domains of life can inserted into microbes such as
Saccharomyces cerevisiae or E. coli, endowing them

with the ability to convert cheap chemical inputs,
such as starch- or cellulose-derived sugars, into
more commercially valuable chemicals.
The products of synthetic biology applied to
industrial fermentation are already in the marketplace and new products are in the works. Large
agro-chemical companies such as Cargill® have
established plants for the conversion of starch to
platform chemicals such as 3-hydroxypropanoate,
which can serve as an intermediate for many other
commodity chemicals. The engineering of E. coli
and Saccharomyces to produce the anti-malarial precursor artemisinic acid by Amyris® is a landmark
achievement in synthetic biology and metabolic
engineering. Elements of their engineered biosynthetic pathway have subsequently been repurposed
to produce fuels and high value chemicals (7),
while Ginkgo Bioworks™ (8) and companies such
as Joule® (9) are engineering microbes to mitigate
greenhouse gases such as methane and CO2 and
produce valuable products, including biofuels. Industrial biosynthesis is not limited to pharmaceuticals and commodity-scale chemicals. Companies
such as Evolva® are working on ways to engineer
yeast to produce vanillin, stevia and even the flavor components of saffron (10), while Pronutria®
is working to efficiently convert CO2 to feed and
medicinal nutrients (11).
The First Synthetic Gene Circuits
In 2000, the first synthetic circuits were made
when Gardner, Cantor and Collins created a genetic toggle switch (12), and Elowitz and Leibler
engineered a repressilator, a synthetic genetic regulatory network designed from scratch to produce
stable oscillations of gene expression (13). Both
of these circuits were model-based, but both also
needed experimental fine-tuning to achieve agreement between model and experimental output.
These experiments were quickly followed by “The
First International Meeting on Synthetic Biology” or SB1.0, which was held in 2004 at MIT
(14). Attended by biologists, chemists, physicists,
engineers and computer scientists, the goal of this
conference was to bring together those scientists
interested in creating and characterizing synthetic
biological systems. This meeting, and smaller ones
like it, laid down the foundation of a new, emerging discipline.
To combat these issues, a public repository, the
Registry of Standard Biological Parts (RSBP), was
founded at MIT by Tom Knight and Drew Endy.
The goal of this repository is to catalog and develop genetic parts into ‘BioBricks®’ that could be
used for the assembly of larger circuits. The BioBrick standard was developed to ensure that parts
could be easily shared and used among synthetic
biologists by requiring submitted parts to conform
to a simplified cloning scheme utilizing four restriction enzymes. However, it became quickly clear
that the task of populating the Registry with biological parts, and the work of characterizing them
to establish their utility, would dwarf the resources
of the relatively small numbers of labs devoted to
synthetic biology. Out of this daunting mission,
and the need to sustainably train a new generation
of synthetic biologists, the International Genetically
Engineered Machine (iGEM) competition was born
(15).
Training the next generation of
bioengineers
Since its inception in 2004, iGEM has evolved into
a highly successful vehicle for training and showcasing a new generation of biological engineers
using the synthetic biology framework. In 2014,
iGEM hosted its 10th annual Jamboree, with over
4,000 participants from across the globe presenting projects that detailed their efforts to model,
build and test genetic devices. Students competed
in a variety of tracks such as Food, Medicine,
Manufacturing and Information Processing. Each
team was also asked to demonstrate that they have
considered the impact and implications of the
technologies they are developing through dialog
with relevant stakeholders. Teams were supported
by various organizations, including NEB (for more
information, visit www.neb.com/igem). To date,
more than 28,000 student competitors have participated in this engineering competition.
A rapidly maturing field
Synthetic Biology as a discipline continues to
grow rapidly. Recent synthetic biology developments include:
A Community to Build From
Circuits Get Complex – In the early 2000s, DNA
circuits continued to advance. More elements were
added (16), and sensing became more diversified
(17,18). Additionally, RNA, not just DNA, was
used in circuit generation (19–21).
As the synthetic biology discipline grew, it quickly
became clear that there needed to be a more efficient way to assemble genetic parts and circuits
(4). Without established methods for assembly
and testing, researchers were forced to ad hoc
experimental designs, wasting time and money by
designing, testing and redesigning constructs.
‘Synthetic’ Used to Investigate ‘Native’ – Beginning in 2009, designed circuits were used to understand native systems through compare/contrast
schemes (22) of engineered versus native systems.
Synthetic Biology was not just limited to engineering new biology; it was also used to investigate and
understand native biology.
www.neb.com
Commercially Valuable Products are Made –
In the 2000s, amino acid biosynthesis was used to
produce commercially valuable products such as
isobutanol (23,24), biodiesel (25) and gasoline (26).
These experiments were a logical extension of fermentation biotechnology and highlighted synthetic
biology’s commercial and environmental promise.
Therapies Engineered – In 2010, Fussenegger
and colleagues engineered a synthetic circuit that,
when inserted into the genome of a mouse mutant
bred to develop hyperuricemia, was able to maintain uric acid homeostasis, essentially correcting an
inborn metabolic defect (33). This demonstrated
the therapeutic promise of synthetic biology.
Assembly of a Whole Bacterial Genome in Yeast
– In 2008, researchers were able to take advantage
of yeast’s remarkable ability to recombine overlapping DNA fragments to assemble an entire genome
in a single step. This method allowed for speedier
assembly of DNA molecules than previous methods
(27,28).
Ongoing Challenges
Synthetic Biology is a young field, but it has
achieved much in a short time period. However,
like all disciplines, it continues to face challenges.
Measurement, Robustness and Predictability
– Aspects of synthetic biology still remain an art.
Genetic circuits often require much “tweaking”
New Genome Editing Tools Emerge – Beginning

synthesized genome (32).
Ethics and Safety – Synthetic Biology, and indeed
all genetic engineering, has provoked concern over
potential misuse, intentional or accidental. There
is active discussion regarding potential impacts
(35). Built-in forms of biological containment are
also an active area of investigation, including the
refinement of genetic “kill switches”, which ideally would ensure that genetic devices could not
survive outside of the laboratory or factory. Government policy has and will continue to weigh in:
information on the ethics of synthetic biology can
be found in the 2010 Presidential Bioethics Commission report on synthetic biology (36). As with
other technologies, a scientifically literate public is
a requirement for nuanced and effective dialog.
Future directions
The past sixty years have seen incredible scientific
and technological advances based on the ability
to compose in DNA. DNA-driven technologies
will continue to absorb developments and ways of
thinking from diverse fields. Advances in materials
sciences, nanotechnology, microfluidics, automated
liquid handling, indeed all the applied sciences,
will drive new applications using cellular systems
and even biological technologies beyond the cell
(37,38). The proliferation and use of these technologies will continue to impact our lives. With
prudence and foresight, they may prove indispensible to our survival.

Your comments – a nice selection:
• Instead of handing over a protocol, my
supervisor gave me the NEB catalog when
I took my first steps (...) almost 15 years
ago. It has been my cloning bible ever
since.
• I still keep and work with this catalog. It is
currently on my bench.
• My Professor told me to order my own copy
of the NEB catalog for reference because she
didn‘t loan her out..
• My supervisor was a very nice good-looking
junior postdoc that tried to invite for a beer.
She declined my offer. I had very little experience in Molecular Biolog and she made
me cut DNA. Used to Biochemistry, I used
undiluted 10x buffer for the reaction. She
laughed at me. Next day after she corrected
my experiment. I found a brand-new NEB
catalog on my motorbike with a note: Start
from the last pages, read 2 chapters a day,
learn fast and we‘ll see. The next days I
cleaned my ignorance with joy, laughs and
finally a beer....
• I was announced „most lazy phD-student
of the lab“ as I always try to avoid tedious
steps in my protocol, such as buffer exchange steps. That is why I always use the
NEB-buffer system to perform my enzymatic
reactions.
• My boss told me that the NEB catalog was
the Bible of the lab and that it will bring me
luck! I am always using it right now (the old
one from 1996-97)!
• Often ridiculous stuff happened to me like
when I made my samples and wanted to
load them on the gel, but I did not put a
comb in. Funny, I was looking and looking but could not figure out what did I do
wrong?! I should emphasize that this was
when I got back from my maternity leave,
so my brain was washed out with dirty diapers...:)
• In the first week of my PhD I went to the
lab on Sunday evening at 7.25 pm to do the
inoculum of E. coli. No one told me that the
building closes at 7.30 pm so I spent a nice
Sunday night in the lab. From that moment
on, I always check opening time of the buildings I work in.

Golden Gate Assembly
advantages of
golden gate assembly
The efficient and seamless assembly of DNA fragments, commonly referred to as Golden Gate
assembly (1,2), has its origins in 1996 when, for the first time, it was shown that multiple inserts
could be assembled into a vector backbone using only the sequential (3) or simultaneous (4) activities
of a single type IIS restriction enzyme and T4 DNA ligase. This method can be accomplished using
Type IIS restriction enzymes, such as BsaI, and can also be used for the cloning of single inserts. The
assembled fragments, or inserts, can either be precloned or in the amplicon form, where the Type IIs
recognition site is introduced through primer design and PCR. The overhang sequence is not dictated
by the restriction enzyme, and allows the design of appropriate four-base overhang sequences that
lead to scarless assembly. The method is efficient and can be completed in one tube in as little as 5
minutes for single inserts, or can utilize cycling steps for multiple inserts. Golden Gate Assembly has
been widely used in the construction of custom-specific TALENs for in vivo gene editing, among other
applications.

added to both ends of a dsDNA
fragment distal to the cleavage
site, such that the BsaI site is
eliminated in the final product.

Near-infrared Imaging in Living Cells
New England Biolabs now offers a unique cell-permeable near-infrared fluorescent probe that enables
live-cell imaging of intracellular proteins using the SNAP-tag® technology.
SNAP-Cell® 647-SiR (SiR-SNAP) is excited at around 650 nm and emits around 670 nm, has a high
quantum efficiency in aqueous media, and is stable against photobleaching. The excellent spectroscopic properties of SNAP-Cell 647-SiR, combined with its high permeability, make it ideally suited
for super-resolution microscopy of cellular proteins in living cells and in vivo.

Rapid PCR Cleanup Enzyme Set –
Test it now and get your FREE Sample*!
The NEB Rapid PCR Cleanup Enzyme Set consists of two recombinant enzymes, Exonuclease I
(Exo I) and Shrimp Alkaline Phosphatase (rSAP). It allows for rapid and complete enzymatic
degradation of residual PCR primers and dephosphorylation of dNTPs subsequent to PCR.
The Rapid PCR Cleanup Enzyme Set enables direct downstream sequencing without the need for
additional purification steps. The components are added directly to the PCR reaction after thermal
cycling and are 100% compatible with commonly used PCR reaction buffers.

PCR products contain residual primer and dNTPs that handicap
downstream sequencing. Rapid PCR Cleanup Enzyme Set
degrades excess primers and dNTPs. Add 1 µl of each enzyme
(Exonuclease I and rSAP) to 5 µl of PCR product (scalable) and
incubate for only 5 minutes at 37°C. The reaction is stopped by
enzyme inactivation at 80°C for 10 minutes. The temperature
regime can be performed in a thermocycler for maximum
convenience.
