WebJan 21, 2024 · DNA molecules consist of two DNA strands, which are twisted around one another to form a spiral shape known as the double helix. The double helix structure of DNA was first discovered in 1953 by James Watson, Francis Crick, and Rosalind Franklin. WebRNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of …
