2. The Discovery of DNA

3. The Structure of DNA “Building Blocks” = Nucleotide
Deoxyribose Sugar
Phosphate
Nitrogenous Base
Nucleotides put together:
Ladder: Uncoiled
Double Helix: 2 long coiled strands
Sides: alternating sugars & phosphates
Middle/ “Rungs” of ladder: 2 nitrogenous bases connected by Hydrogen bonds

4. Nucleotide Structure

5. Structure of DNA: Base Pairing
4 Nitrogen Bases:
Adenine
Guanine
Thymine
Cytosine
Base Pairing:
A ---- T
G ---- C
} Purine
} Pyrimidine
