are nucleic acids made up of?
A
C,H,O,N,P
2
Q
What are the two nucleic acids?
A
DNA (Deoxyribonucleic acid)
RNA (Ribonucleic acid)
3
Q
What are nucleic acids for?
A
- Carry genetic information
- To make proteins
4
Q
What is the monomer of a nucleic acid?
A
Nucleotide
5
Q
What are the 3 parts of a nucleotide?
A
Phosphate group, pentose sugar, nitrogenous base
6
Q
What is the charge of the phosphate group, and how does this help?
A
Negative
So DNA can interact with positively charged histones to form a stable chromosome.

A
DNA - A, G (purines)
- C,T (pyrimadines)
RNA - A,G (purines)
- C,U (pyrimadines)
