Ribonucleic acid (RNA) is a polynucleotide chain like DNA but differs in three respects: it uses ribose sugar (not deoxyribose), the base uracil in place of thymine, and is normally single-stranded (a few viruses have double-stranded RNA). RNA is usually not the hereditary material (an exception is the tobacco mosaic virus), and, being single-stranded, does not obey Chargaff's purine=pyrimidine rule.

Three types of cellular RNA carry out protein synthesis:

• mRNA (messenger RNA) — a linear single strand carrying the genetic code from DNA that specifies the amino-acid sequence of a polypeptide; the stretch coding for one polypeptide is a cistron; ~3% of cellular RNA. …
