Question

What are the three components of DNA nucleotides?

A) Nitrogenous bases, phosphate group, and deoxyribose.
B) Nitrogenous bases, phosphate group, and thymine.
C) Five carbon sugar, Nitrogenous bases, and deoxyribose.
D) Phosphate group, Ribose, and Nitrogenous bases.

Answer 1

The correct components of DNA nucleotides are nitrogenous bases, phosphate group, and deoxyribose, making option A the right answer.

Step-by-step explanation:

The three components of DNA nucleotides are a nitrogenous base, a phosphate group, and deoxyribose, which is a five-carbon sugar. The nucleotide is named depending on the nitrogenous base it contains, which can be a purine such as adenine (A) and guanine (G), or a pyrimidine such as cytosine (C) and thymine (T). Out of the options provided, the correct answer is A) Nitrogenous bases, phosphate group, and deoxyribose.
