The structure and chemistry of nucleic acids is fundamental to their function, from the DNA double helix discovered by Watson and Crick to the intricate secondary and tertiary structures adopted by ...

not nucleic acid, but by the late 1940s, DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA ... to form the iconic double helix structure. RNA is usually single-stranded but can form complex ...
