Overview
DNA, or deoxyribonucleic acid, is the fundamental molecule that carries genetic information in all living organisms. Its structure is famously known as a double helix, which resembles a twisted ladder. This unique shape allows DNA to store vast amounts of information efficiently. Each rung of the la...
