A. nucleotides
B. polypeptides

A?

A :Nucleotides is correct

Correct! DNA is a nucleic acid made up of monomers called nucleotides.

To arrive at this answer, you can rely on some key concepts. Understanding the basic structure of DNA is important here. DNA is a double-stranded molecule that consists of two long chains of nucleotides held together by hydrogen bonds. Each nucleotide is composed of three components: a deoxyribose sugar, a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

By recalling this information, you can determine that the monomers that make up DNA are called nucleotides. Each nucleotide is composed of a sugar, a phosphate group, and a nitrogenous base. Therefore, the correct answer is A. nucleotides.
