DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. DNA is comprised of two long strands that form a spiral called a double helix. Each of the two strands of the DNA molecule is a chain of smaller molecules.Each link in the chain is composed of one sugar molecule, one phosphate molecule and one nucleotide molecule.There are four types of nucleotide molecules, or bases, in DNA: adenine (A), thymine (T), guanine (G) and cytosine (C).NA. RNA, or ribonucleic acid, is part of a group of molecules known as the nucleic acids which, along with lipids, carbohydrates and proteins, comprise the major macromolecules essential for all known forms of life.
