How many different types of nucleotides exist?
A
4
B
3
C
2
D
1
Explanation: 

Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Detailed explanation-2: -Molecules called nucleotides, on opposite strands of the DNA double helix, that form chemical bonds with one another. These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together. There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-3: -Understanding DNA replication Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Detailed explanation-4: -RNA is composed of four individual nucleotides. These four nucleotides include adenine, cytosine, guanine, and uracil, which replaces thymine in DNA.. A nucleotide consists of a phosphate group, sugar, and a phosphate group.

Detailed explanation-5: -The five bases that are found in nucleotides are often represented by their initial letter: adenine, A; guanine, G; cytosine, C; thymine, T; and uracil, U. Note that A, G, C and T occur in DNA; A, G, C and U occur in RNA.
