- The basic structure of DNA is in a shape called the Double Helix.
- The Double Helix is made up of bases that bond together through Hydrogen Bonds
2. The Double Helix has a backbone that keeps the bases together.
- This Backbone is a sugar named Deoxyribose, and the Bases are Adenine, Thymine, Guanine, and Cytosine.
3. Each base pairs up with it's opposite to make a hydrogen bond.
- Thymine pairs up with Adenine (A-T) or (T-A)
- Guanine pairs up with Cytosine (G-C) or (C-G)
4. Nucleotides are made up of a sugar, a phosphate, and one of the four pyrimidine bases (Guanine, Thymine, Adenine, or Cytosine)
