What is DNA?

DNA (deoxyribonucleic acid) is one of the most important molecules 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 the necessary genetic information.

DNA sequencing has revolutionized medicine and biomedical research. For example, DNA analysis can tell doctors which drug might work best against a particular cancer. But current technology usually sequences only short stretches of DNA and can take hours or days.
