Study Notes
Nucleotide Basics
- Nucleotides serve as the fundamental units in the structure of DNA.
Composition of Nucleotides
- Each nucleotide consists of a phosphate group, a five-sided sugar (deoxyribose), and one nitrogen base.
Nitrogen Base Variants
- There are four unique nitrogen base variants in DNA:
- Two are purines (double-ringed): Adenine (A) and Guanine (G).
- Two are pyrimidines (single-ringed): Thymine (T) and Cytosine (C).
Sugar Component
- The five-sided sugar found in DNA nucleotides is deoxyribose.
Characteristics of Nitrogen Bases
- Single-ring nitrogen bases: Thymine (T) or Cytosine (C).
- Double-ring nitrogen bases: Adenine (A) or Guanine (G).
Base Pairing Rules
- Adenine specifically pairs with Thymine (A-T).
- Guanine exclusively pairs with Cytosine (G-C).
