Study Notes
DNA Structure and Composition
- A DNA nucleotide consists of three essential components:
- Phosphate group
- Deoxyribose sugar
- Nitrogenous base
DNA Nitrogenous Bases
- DNA is made up of four main nitrogenous bases:
- Adenine (A)
- Thymine (T)
- Guanine (G)
- Cytosine (C)
Base Pairing Rules
- Adenine pairs with Thymine (A-T)
- Cytosine pairs with Guanine (C-G)
Significance of Base Pairing
- The specific pairing of adenine with thymine and cytosine with guanine is crucial for the structure of the DNA double helix and the fidelity of DNA replication.
