Question

What are nucleic acids? Discuss the structure of DNA with a diagram.

Hint:

DNA follows Chargaff's rule: A pairs with T, and C pairs with G via hydrogen bonds.

Answer 1

Step 1: Definition: Nucleic acids (DNA & RNA) are biomolecules composed of nucleotides, responsible for genetic information storage. Step 2: Structure of DNA:
- Double-helix model by Watson and Crick.
- Consists of phosphate backbone and nitrogenous bases (A, T, C, G).
- Complementary base pairing: A-T, C-G. 

Step 3: Diagram: \[ \text{(Include diagram of DNA double-helix)} \]
