Verified step by step guidance1
Step 1: Understand the structure of nucleic acids. Nucleic acids, such as DNA and RNA, are polymers made up of repeating units called monomers.
Step 2: Recall the definition of a monomer. A monomer is a small molecule that can bind chemically to other molecules to form a polymer.
Step 3: Identify the specific monomers of nucleic acids. Nucleotides are the building blocks (monomers) of nucleic acids. Each nucleotide consists of three components: a phosphate group, a sugar (either ribose or deoxyribose), and a nitrogenous base.
Step 4: Compare the options provided. Monosaccharides are simple sugars, fatty acids are components of lipids, and amino acids are the monomers of proteins. None of these are the monomers of nucleic acids.
Step 5: Conclude that nucleotides are the correct answer because they are the specific monomers that make up nucleic acids.
