Question

which of the following is a monomer of nucleic acids? options (colored bars): amino acid, fatty acid, nucleotide, monosaccharide. (context: biomolecules (updated 2023), question 9)

Explanation:

To determine the monomer of nucleic acids, we recall biological concepts:

• Amino acids are monomers of proteins.
• Fatty acids are part of lipids (along with glycerol).
• Monosaccharides are monomers of carbohydrates.
• Nucleotides are the building blocks (monomers) of nucleic acids (DNA and RNA), as nucleic acids are polymers made by linking nucleotides together.

Answer:

B. Nucleotide (assuming the orange option is labeled "Nucleotide" as per the image's text)
