substance containing the genetic information of a cell

The substance containing the genetic information of a cell is called DNA (Deoxyribonucleic Acid). DNA is a double-stranded molecule that carries the genetic instructions necessary for the development, function, growth, and reproduction of all living organisms. It is comprised of four nucleotide bases - adenine (A), thymine (T), cytosine (C), and guanine (G) - that form a specific code, which determines the characteristics and traits of an organism.
