Question

a nucleotide of dna may contain adenine, guanine, cytosine, or thymine. what is each of these components?
a. 5 - carbon sugar
b. nitrogenous base
c. phosphate group
d. nucleic acid

Explanation:

A nucleotide is composed of three parts: a 5 - carbon sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base. Adenine, guanine, cytosine, and thymine are the four types of nitrogenous bases found in DNA. A 5 - carbon sugar is deoxyribose in DNA. A phosphate group is another component of a nucleotide but is not the nitrogen - containing part. Nucleic acid is the larger molecule (DNA or RNA) of which nucleotides are the building blocks.

Answer:

B. nitrogenous base
