Nucleotides
B
Monosaccharides
C
Fatty acids
D
Amino acids
Verified step by step guidance
1
Understand the structure of nucleic acids: Nucleic acids, such as DNA and RNA, are polymers made up of repeating units called monomers.
Identify the specific monomers of nucleic acids: The monomers that make up nucleic acids are nucleotides, which consist of three components: a nitrogenous base, a pentose sugar, and a phosphate group.
Eliminate incorrect options: Monosaccharides are the monomers of carbohydrates, fatty acids are components of lipids, and amino acids are the monomers of proteins. None of these are involved in forming nucleic acids.
Focus on the correct option: Nucleotides are the building blocks of nucleic acids, and they polymerize through phosphodiester bonds to form the backbone of DNA and RNA.
Conclude the reasoning: Based on the structural and functional roles of nucleotides, they are the correct answer as the monomers that make up nucleic acids.
