BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Deoxyribo-nucleic Acid (DNA) consists of simple sugar, phosphate and four nitrogen bases.

Detailed explanation-2: -Nucleotide 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.

Detailed explanation-3: -A nucleotide consists of a sugar molecule, nitrogenous base and a phosphate group.

Detailed explanation-4: -Each nucleotide consists of a phosphate group, a nitrogenous base-adenine (A), thymine (T), cytosine (C), or guanine (G)-and deoxyribose. DNA’s sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. Four carbons plus an oxygen are part of the five-sided ring.

Detailed explanation-5: -The combination of a sugar phosphate group and a base constitutes anucleotide. The double helix is made from two polynucleotide chains, each of which consists of a series of 5′-to 3′-sugar phosphate links that form a backbone from which the bases protrude.
