DNA contains instructions for protein synthesis from "summary" of NCERT Solutions - Biology for Class 12th by Dr. Madhurbhashini,Sargam Hans,Shanya Hans
DNA, or deoxyribonucleic acid, is a molecule that carries genetic instructions for the development, functioning, growth, and reproduction of all living organisms. It is a long, double-stranded helical structure composed of nucleotides, each containing a sugar molecule, a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The instructions encoded in DNA are responsible for determining the characteristics of an organism, such as its physical traits, biochemistry, and behavior. One of the key functions of DNA is to provide the instructions necessary for protein synthesis. Proteins are essential molecules that perform a wide variety of functions in living organisms, such as catalyzing biochemical reactions, providing structural support, and regulating gene e...
