HUMAN NUTRITION

Detailed explanation-1: -Today, this molecule is called DNA. Nearly all of the cells within a single organism include exactly the same DNA. DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-2: -The genetic information of an organism is stored in DNA molecules.

Detailed explanation-3: -Nucleic Acids Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that play multiple cellular roles, including protein synthesis.
