| RNA, small nuclear | Short chains of RNA found in the nucleus. Their function is to remove the introns (nontranslated intervening sequences) from mRNA precursors, thereby bringing the two exons (coding segments) together into correct juxtaposition for enzymatic splicing at the correct point. The resulting mRNA is now ready to leave the nucleus. (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) |
| RNA, transfer, glu | A transfer RNA which is specific for carrying glutamic acid to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, gly | A transfer RNA which is specific for carrying glycine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, his | A transfer RNA which is specific for carrying histidine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
