Question

number correct 12 number incorrect 3 nucleic acids are polymers. the monomer (building block) of a nucleic acid is known as a(n)... a. amino acid b. polysaccharide c. monosaccharide d. nucleotide

Explanation:

To solve this, we analyze each option:

• Option A: Amino acids are monomers of proteins, not nucleic acids. Eliminate A.
• Option B: Polysaccharides are polymers of monosaccharides (carbohydrates), not related to nucleic acids. Eliminate B.
• Option C: Monosaccharides are monomers of carbohydrates (like polysaccharides), not nucleic acids. Eliminate C.
• Option D: Nucleotides are the monomeric units (building blocks) that polymerize to form nucleic acids (DNA and RNA). So this is correct.

Answer:

D. Nucleotide
