DNA

Definition of DNA as it relates to Science, Genetics

DNA, or deoxyribonucleic acid, is the fundamental hereditary material found in the cells of every living organism. It carries the genetic instructions used in the growth, development, functioning, and reproduction of all known organisms. DNA is a double-stranded helical molecule composed of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. The nucleotide subunits are classified into four types according to their nitrogenous bases: adenine, guanine, cytosine, and thymine, which pair specifically with each other through hydrogen bonding (Adenine with Thymine; Guanine with Cytosine). The sequence of these nucleotides along the DNA chain determines the genetic information encoded in it. This information is used as a blueprint for the synthesis of proteins and RNA molecules, which are essential components of living organisms. DNA also has the remarkable ability to replicate itself accurately, allowing genetic information to be passed down from generation to generation. As such, DNA serves as the primary carrier of genetic information in biological systems, underpinning the principles of genetics and evolution.
