Webb18 dec. 2024 · RNA is a polymer consisting of chains of nucleotides. These are nitrogenous bases attached to phosphate groups and ribose sugars. The four bases in RNA are adenine, uracil, cytosine and guanine. RNA can form into double-stranded structures, such as during translation, when mRNA and tRNA molecules pair.

But the concept of RNA as a primordial molecule is older, hypothesized by Crick (1968), Orgel (1968), and Woese (1967). Noller subsequently provided evidence that ribosomal ... gel vanish oxi action

The RNA transcripts are considerably modified in the nucleus during maturation, and during transcription of DNA into RNA, short hybrids of the A conformation appear.
