Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.

Detailed explanation-2: -DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.

Detailed explanation-3: -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: -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-5: -Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
