BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate. InFigure 2, the nitrogenous base is enclosed in the red square on the right, while the phosphate is enclosed in the blue square on the left. The remainder of the molecule forms the pentose sugar.

Detailed explanation-2: -Each nucleotide consists of a five-carbon (pentose) sugar, a phosphate group, and one of five different nitrogenous bases. These five nitrogenous bases include: adenine (A), thymine (T), cytosine (C), guanine (G), and uracil (U).

Detailed explanation-3: -A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.

Detailed explanation-4: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).

Detailed explanation-5: -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.
