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: -DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides.

Detailed explanation-3: -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-4: -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-5: -Nucleic acids are polymers of nucleotides joined by covalent (phosphodiester) bonds formed between their sugar and phosphate groups.
