Verified step by step guidance

Understand the structure and function of nucleic acids: Nucleic acids, such as DNA and RNA, are macromolecules responsible for storing and transmitting genetic information. Their structure is composed of repeating monomer units.

Identify the monomer unit of nucleic acids: The monomer unit of nucleic acids is the nucleotide, which consists of three components: a phosphate group, a pentose sugar (either ribose or deoxyribose), and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).

Compare the given options: Fatty acids are monomers of lipids, amino acids are monomers of proteins, monosaccharides are monomers of carbohydrates, and nucleotides are monomers of nucleic acids.

Eliminate incorrect options: Fatty acids, amino acids, and monosaccharides are not related to nucleic acids. Nucleotides are the correct monomer unit for nucleic acids.

Conclude the reasoning: Based on the structural and functional relationship, the correct answer is 'Nucleotide,' as it is the building block of nucleic acids.
