What are the four types of nitrogen bases of DNA nucleotides?

a) Adenine (A)

b) Guanine (G)

c) Cytosine (C)

d) Thymine (T)

Explanation:

There are four types of nitrogenous bases in DNA

a) Adenine (A)

b) Guanine (G)

c) Cytosine (C)

d) Thymine (T)

Both the Adenine and Thymine are complimentary to each other while Guanine and Cytosine are complimentary to each other. The nucleotide are named based on the nitrogenous base in it.

RNA has a different nitrogenous base instead of thymine, known as uracil.
