| RNA, ribosomal, 5.8s | Constituent of the 60s subunit of eukaryotic ribosomes. 5.8s rrna is involved in the initiation of polypeptide synthesis in eukaryotes. (12 Dec 1998) |
| RNA, ribosomal, 5s | Constituent of the 50s subunit of prokaryotic ribosomes containing about 120 nucleotides and 34 proteins. It is also a constituent of the 60s subunit of eukaryotic ribosomes. 5s rrna is involved in initiation of polypeptide synthesis. (12 Dec 1998) |
| RNA, satellite | Small, linear single-stranded RNA molecules functionally acting as molecular parasites of certain RNA plant viruses. Satellite rnas exhibit four characteristic traits: 1) they require helper viruses to replicate; 2) they are unnecessary for the replication of helper viruses; 3) they are encapsidated in the coat protein of the helper virus; 4) they have no extensive sequence homology to the helper virus. Thus they differ from satellite viruses which encode their own coat protein, and from the genomic RNA (=RNA, viral) of satellite viruses. (12 Dec 1998) |
| RNA splicing | <molecular biology> The removal of introns from primary RNA transcripts. (23 Aug 1998) |
| RNA splicing pattern | <molecular biology> The combination of DNA sequences copied from a gene by messenger RNA. The mRNAs transcribed from a single gene may splice together different parts of the sequence of the gene. (23 Aug 1998) |
| RNA, transfer | In cooperation with the ribosomes, transfer RNA brings (transfers) activated amino acids into position along the messenger RNA template. The abbreviation for transfer RNA is trna. (12 Dec 1998) |
| RNA, transfer, ala | A transfer RNA which is specific for carrying alanine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acyl | Intermediates in protein biosynthesis. The compounds are formed from amino acids, ATP and transfer RNA, a reaction catalyzed by aminoacyl trna synthetase. They are key compounds in the genetic translation process. (12 Dec 1998) |
| RNA, transfer, arg | A transfer RNA which is specific for carrying arginine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, asn | A transfer RNA which is specific for carrying asparagine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, asp | A transfer RNA which is specific for carrying aspartic acid to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, cys | A transfer RNA which is specific for carrying cysteine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, gln | A transfer RNA which is specific for carrying glutamine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
