Ribonucleic acid; a cellular polynucleotide chemically related to DNA except that RNA is single-stranded, contains uracil rather than its counterpart thymine, and has ribose sugars in the backbone; some forms of RNA also contain the genetic information necessary for protein synthesis (mRNA), whereas other forms are structural (rRNA) or catalytic (tRNA). Aka nongenetic RNA.

See antisense RNA, charged tRNA, double-stranded RNA, DNAlike RNA, genetic RNA (gRNA), heterogenous messenger RNA (hmRNA), heterogenous nuclear RNA (hnRNA), pre-mRNA, sense RNA, small RNAs, soluble RNA (s RNA), suppressor tRNA, and template RNA.
