DNA is the genetic material in all living organisms from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
The discovery that DNA is the genetic material in all living organisms was a groundbreaking moment in the field of biology. This finding revolutionized our understanding of heredity and paved the way for countless advancements in genetics. DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms. It is composed of two long chains of nucleotides twisted into a double helix structure. The genetic information encoded in DNA is stored in the sequence of its four nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up in a specific manner (A with T, and G with C) to form the "r...
