Question

How many types of nucleotides are in DNA, and how do they differ?

Answer 1

There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C). A base on one of the chains that makes up DNA is chemically bonded to a base on the other chain.

Answer 2

Answer:

Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. ... Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring.
