Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The monomer of a nucleic acid is called ____
A
an amino acid
B
a fatty acid
C
a monosaccharide
D
a nucleotide
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: -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.

Detailed explanation-3: -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-4: -Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.

Detailed explanation-5: -A nucleotide is a monomer that serves as the building blocks for deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Examples of nucleotides are ribonucleotides or deoxyribonucleotides.
