BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine.

Detailed explanation-2: -A long biological molecule made of smaller subunits called nucleotides. Both DNA and RNA are examples of nucleic acids.

Detailed explanation-3: -Nucleic acids consist of 3 subunits.

Detailed explanation-4: -The nucleotides have a similar structure with three ‘subunits’: A phosphate group. A sugar group : deoxyribose in DNA and ribose in RNA. A nitrogenous base : adenine, cytosine, guanine, thymine or uracil.

Detailed explanation-5: -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.
