Deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions for building and operating an organism. DNA is made up of two strands that are twisted together in a double helix. Each strand is made up of a series of nucleotides. Nucleotides are made up of a sugar, a phosphate group, and a nitrogenous base. The nitrogenous bases are adenine (A), guanine (G), cytosine (C), and thymine (T). The order of the nitrogenous bases in DNA is what determines the organism’s genetic information.
DNA is responsible for controlling the function of every living cell. It contains all the information necessary for the growth, development, and function of an organism. DNA is organized into structures called chromosomes, which are located in the nucleus of the cell.
DNA is found in the nucleus of every cell in the body. It is also found in mitochondria, which are the energy-producing organelles in cells. DNA is responsible for storing and transmitting genetic information from one generation to the next. It is also responsible for controlling the cell’s activities, such as growth, development, and reproduction.
