The four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).
These bases form specific pairs (A with T, and G with C).
<h3>What is DNA nucleotides?</h3>
Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate.
They serve as monomeric units of the nucleic acid polymers –
- Deoxyribonucleic acid
- Ribonucleic acid,
So therefore, the four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).
