Detailed explanation-1: -The three components of a nucleotide are nitrogenous base, sugar and phosphate.
Detailed explanation-2: -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). In RNA, the base uracil (U) takes the place of thymine.
Detailed explanation-3: -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.
Detailed explanation-4: -The sugar is the 3’ end, and the phosphate is the 5’ end of each nucleiotide. The phosphate group attached to the 5’ carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3’ carbon of the next nucleotide.
Detailed explanation-5: -Phosphate Group in DNA Deoxyribonucleic acid (DNA) is made up of the building blocks called nucleotides. Each nucleotide comprises of three components such as a phosphate group, a nitrogenous base, and a deoxyribose.
