DNA (deoxyribonucleic acid) is an extremely important molecule for life on Earth. All known living organisms use genetic information in their cell growth and development, division, and function – and DNA is responsible for encoding that information. Structurally, DNA is a double helix (much like a spiral staircase), and each step in the chain is part of a long code that conveys genetic information.
