8.L.2 Understand how biotechnology is used to affect living organisms.
8.L.2.1 Summarize aspects of biotechnology including:
• Specific genetic information available
• Careers
• Economic benefits to North Carolina
• Ethical issues
• Implications for agriculture
Understanding of the microbial world has led to the emerging field of biotechnology which has
given us many advances and new careers in medicine, agriculture, genetics, and food science.
Biotechnology, while it has benefited North Carolina in many ways, has also raised many
ethical issues for an informed community to consider. As we increase our knowledge and make
advances in technology we are able to reduce the threat of microbial hazards. Biotechnology
affects us in every area of our lives: our food, water, medicine and shelter. Uses of modern
biotechnology include: making medicine in large quantities (e.g. penicillin) and human insulin
for the treatment of diabetes, combating crime through DNA testing and forensic testing,
removing pollution from soil and water (bioremediation), and improving the quality of
agricultural crops and livestock products. Some new areas such as Genetic Modification (GM)
and cloning are controversial.

DNA: Review
8.L.2.1
DNA, short for deoxyribonucleic acid, is
the molecule that contains
the genetic code of organisms. This
includes animals, plants, protists, archaea
and bacteria.
DNA is in each cell in the organism and
tells cells what proteins to make. A cell's
proteins determine its function. DNA
is inherited by children from their parents.
This is why children share traits with their
parents, such as skin, hair and eye color.
The DNA in a person is a combination of
the DNA from each of their parents.
http://simple.wikipedia.org/wiki/DNA
Biotech has been around a while!
8.L.2.1
•Approximately 7,000BC (give or take a few years)
•Produced with milk (from cow or goat) and various enzymes
from living animals
•Type of enzyme used depends on the desired cheesy outcome
•Chymosin®, a product of biotechnology, replaces the more
expensive and variable enzyme rennin, obtained from animal
sources.
•Prehistoric Evidence of Bread (but it was flat)
•Yeast, eukaryotic, single-celled fungi, is what causes
bread to rise (carbon dioxide) and wine/beer to ferment
(producing ethanol)
•The yeast eats the sugar in the bread material and
breathes out carbon dioxide causing the little air pockets
in bread.

Agricultural Biotechnology
8.L.2.1
Biotechnology: the use of cells and biological molecules to make a
product or solve a problem
Mrs. R. Parker
Problem:
The population of the world is increasing. How will we
produce enough high-quality food for the increasing
population?
Pasteurization of Milk
1861
Problem: Food-borne illness
Solution: Pasteurization
http://strausfamilycreamery.com/field-to-bottle/artisan-dairy-craft/gently-pasteurized-milk
http://www.childrensmuseum.org/biotech-timeline
8.L.2.1
Pasteurization
is the process by which milk is heated above
145° F for at least 30 minutes, and then quickly
cooled. The procedure kills all harmful bacteria,
but does not affect the taste or food value. Louis
Pasteur invented this procedure to help rid
foods and drinks of harmful bacteria, which
were making millions of people sick every year.
Chymosin
1990
Problem: (1960s) shortage of rennet, an enzyme
needed to make cheese
Solution: The use of bacteria to produce Chymosin, a
suitable replacement for rennet .

8.L.2.1
FlavrSavr Tomato
1994
8.L.2.1
Problem: Tomatoes go bad too fast!
Solution: The FlavrSavr Tomato! A gene was inserted
that interferes with rot-causing proteins. This means that
the tomato can ripen on the vine, be shipped to its
destination, and be eaten before rotting takes place.

Pest-Resistant Crops
8.L.2.1
Problem: Pests swoop in and eat crops, causing a loss in
revenue ($) for farmers and a shortage in supply.
Solution for Cotton (applies to many other crops):
A gene is inserted into the seeds that produces proteins
that are toxic to certain insects but allow others that are
helpful to live.

Herbicide-Resistant Crops
Problem: Excessive weed growth forces crops to
compete for sunlight and nutrients, often leading to
significant losses.
Solution:
Genetically modified seeds (created to be resistant to
the chemicals used to kill weeds).

pests not only in cotton crops but also in neighboring fields of soybeans and
corn.

Biotechnology and Biodiversity
8.L.2.1
Life
variety
Biotechnology helps in the conservation of plant life, so an
entire plant can be grown from one cell of an endangered
plant species. This allows us to KEEP plant diversity.
Biotechnology has caused biodiversity (in relation to seeded
food crops) to decline because they risk destroying the
original genetic make-up of the seeds.
Bioinformatics
8.L.2.1
Life
People + information + technology
Bioinformatics is the application of computer technology to
the management of biological information.
The human genome project! It’s goal is to find the sequence
of the human genome – 3 billion base pairs – to understand
human disease and aid in creation of treatments.
