Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The monomers (building blocks) of DNA and RNA are ____
A
nucleotides
B
amino acids
C
polypeptides
D
glucose
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). The sugar and phosphate create a backbone down either side of the double helix.

Detailed explanation-2: -Nucleotide A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-3: -The monomers of DNA and RNA are the nucleotides. The nucleotides are observed to combine with each other in order to produce a polynucleotide which can either be a DNA or RNA.

Detailed explanation-4: -A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.

Detailed explanation-5: -Answer and Explanation: Nucleotides are the monomers (building blocks) of nucleic acids.
