Ribonucleic acid (RNA) occurs in different forms within organisms and serves many different roles. Listed here are the types of RNA, grouped by role. Abbreviations for the different types of RNA are listed and explained.
Since RNA is charged, metal ions such as Mg 2+ are needed to stabilise many secondary and tertiary structures. [17] The naturally occurring enantiomer of RNA is D-RNA composed of D-ribonucleotides. All chirality centers are located in the D-ribose. By the use of L-ribose or rather L-ribonucleotides, L-RNA can be synthesized.
Ribonucleic acid (RNA) is an important nucleic acid consisting of a string of covalently bound nucleotides The main article for this category is RNA . Wikimedia Commons has media related to RNA .
A study of several thousand RNA viruses has shown the presence of at least five main taxa: a levivirus and relatives group; a picornavirus supergroup; an alphavirus supergroup plus a flavivirus supergroup; the dsRNA viruses; and the -ve strand viruses. [22] The lentivirus group appears to be basal to all the remaining RNA viruses. The next ...
The transcriptome encompasses all the ribonucleic acid (RNA) transcripts present in a given organism or experimental sample. [8] RNA is the main carrier of genetic information that is responsible for the process of converting DNA into an organism's phenotype.

All living cells contain both DNA and RNA (except some cells such as mature red blood cells), while viruses contain either DNA or RNA, but usually not both. [15] The basic component of biological nucleic acids is the nucleotide, each of which contains a pentose sugar (ribose or deoxyribose), a phosphate group, and a nucleobase. [16]
