BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The basic unit of a nucleic acid is a nucleotide. It is formed by a nitrogenous base, a sugar and a phosphate group. The nitrogenous bases that bind to the sugar are of two types; purines consisting of adenine and guanine and pyrimidines consisting of cytosine, thymine in DNA and uracil in RNA.

Detailed explanation-2: -A nucleotide consists of a sugar molecule, a nitrogenous base, and a phosphate group.

Detailed explanation-3: -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-4: -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-5: -Nucleoside is the combination of only nitrogen base and pentose sugar. There is no phosphate group present in the nucleoside. The nucleic acid is the polymer made up of the nitrogen bases.
