What is the structure of the molecule to store information?

The molecule primarily responsible for storing information in biological systems is DNA (deoxyribonucleic acid). DNA consists of two long strands forming a double helix, with each strand made up of a backbone of sugar and phosphate groups, and nitrogenous bases (adenine, thymine, cytosine, and guanine) that pair specifically (A with T, C with G). The sequence of these bases encodes genetic information, which is crucial for the development and functioning of living organisms. Additionally, RNA (ribonucleic acid) plays a role in information transfer and expression, particularly in protein synthesis.
