DNA, 脱氧核糖核酸
(biochemistry) a chemical substance that carries the genetic information, which is present in every cell and some viruses
Deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions for the development, functioning, and reproduction of all living organisms. DNA is made of two long, twisted strands that form a spiral shape, and it carries the hereditary information used to build and maintain an organism. Each segment of DNA, called a gene, provides instructions for making specific proteins that influence traits and manage various bodily functions. DNA is found in the cells of all living things and is passed from parents to children, directing growth and development.
