Ch. 12: DNA
Objective: Students will be able to model
DNA structure.
Deoxyribonucleic Acid (DNA)
Structure
Nucleic Acid
Double Helix
Twisted ladder
Backbone
Phosphate and sugar (deoxyribose)
Rungs
Made up of 4 different bases
T= Thymine--1 ring
A= Adenine--2 rings
C= Cytosine--1 ring
G= Guanine--2 rings
Made of Nucleotides
1 nucleotide = 1 sugar, 1
phosphate, and 1 base
3 Rules DNA follows:
1. 1 ring always hooks to a 2 ring
2. A always binds to T and C always
binds to G (Chargaff's Rule)
3. The "sides" of the ladder go in
opposite directions=antiparallel

Objective:
Students will be able to model DNA
structure and recognize the monomers
that make up DNA.
Modeling DNA
• 1 monomer of a nucleic acid like DNA
is a nucleotide.
DNA structure
03/22/13
Hydrogen bond (white rod)
Directions:
1. Build the following using the model
parts:
• 1 nucleotide using Cytosine (blue)
• 1 nucleotide using Guanine (yellow)
• 1 nucleotide using Thymine (green)
• 1 nucleotide using Adenine (orange)
2. Draw each nucleotide in your notebook.
