What is the monomer of nucleic acids?
A
Glycerol
B
Monosaccharides
C
Amino Acids
D
Nucleotides
Explanation: 

Detailed explanation-1: -The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-2: -Nucleic acid monomers are called nucleotides; protein monomers are called amino acids; lipid monomers are called fatty acids; and carbohydrate monomers are called monosaccharides (MAH-nuh-SA-kuh-riyd). All types of monomers are organic molecules, meaning that they contain carbon-to-carbon bonds.

Detailed explanation-3: -In case of nucleic acids, monomers are the nucleotides composed of nitrogenous base, pentose sugar, and phosphate group whereas DNA and RNA are considered as polymer of nucleic acids. DNA and RNA are composed of monomers termed as nucleotides.

Detailed explanation-4: -All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA.

Detailed explanation-5: -Nucleotides are the monomers of nucleic acids. A monomer is a single molecule that is linked together many times to form a polymer. Nucleic acid polymers are formed by many nucleotide molecules linked together. Each individual nucleotide has a sugar group, a phosphate group, and a nitrogenous base.
