Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Both DNA and RNA are made up of building blocks known as
A
nucleotides
B
complementary base pairs
C
amino acids
D
genes
Explanation: 

Detailed explanation-1: -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-2: -The molecules that serve as the building blocks of DNA and RNA. Nucleotides consist of one nitrogenous base – adenine, cytosine, guanine, or thymine (uracil in RNA), a sugar (deoxyribose in DNA, ribose in RNA) and a phosphate group.

Detailed explanation-3: -Definition. 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-4: -Proteins, the building blocks of life are long chains of amino acids. Nucleic acids i.e. DNA and RNA are made up of building blocks called nucleotides.
