|---|---|
| coding sequence | The portion of DNA that codes for transcription of messenger RNA. See: exon. (05 Mar 2000) |
| coding strand | The strand of duplex DNA that has the same sequence as the mRNA (except that mRNA contains ribonucleotides instead of deoxyribonucleotides). Synonym: sense strand. (05 Mar 2000) |
| nonsense triplet | A trinucleotide (codon) in which a base change to a termination codon results in premature termination of the growing polypeptide chain and, consequently, incomplete protein molecules, a termination codon. (05 Mar 2000) |
| triplet | <microscopy> A combination of three simple lenses cemented together. Two positive lenses with a negative lens between them can produce a well-corrected system. (05 Aug 1998) |
| triplet state | A second excited state of a molecule (e.g., chlorophyll) produced by absorption of light to produce the singlet state, then loss of some energy (fluorescence) to arrive at the longer-lived triplet state The molecule may remain sufficiently long in the triplet state for a second activating light quantum to be effective in producing a "second triplet" state, obviously at still a higher level of excitation, hence reactivity. Alternatively, it may lose the triplet state energy directly and return to the ground state. (05 Mar 2000) |
| acceptor RNA | rNA |
| antisense RNA | <molecular biology> A complementary RNA sequence that binds to (and thus blocks the transcription of) a naturally-occuring (sense) messenger RNA molecule. These proteins can be used to selectively turn off production of certain proteins or block viral genetic instructions, by marking them for destruction by cellular enzymes, in order to prevent the building of new virus or the infection of new cells. (09 Oct 1997) |
| bacteriophage T3 RNA polymerase | <enzyme> Used for the rapid generation of strand-specific RNA molecules that can be used for the identification of genes in hybridization experiments Registry number: EC 2.7.7.- Synonym: t3 RNA polymerase (26 Jun 1999) |
| cap II RNA(nucleoside-2'-)methyltransferase | <enzyme> Converts cap i-terminated mRNA to cap II-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap II methylase (26 Jun 1999) |
| cap I RNA (nucleoside-2'-)methyltransferase | <enzyme> Converts cap 0-terminated mRNA to cap i-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap I methylase (26 Jun 1999) |
| p68 RNA helicase | <enzyme> An RNA helicase isolated from uv-induced tumours in mice; amino acid sequence has been determined Registry number: EC 2.7.7.- Synonym: dead box helicase p68 (26 Jun 1999) |
| masked messenger RNA | <molecular biology> Long lived and stable mRNA found originally in the oocytes of echinoderms and constituting a store of maternal information for protein synthesis that is unmasked (derepressed) during the early stages of morphogenesis. In these early stages the rate of cell division is so rapid that transcription from the embryonic genome cannot occur. Undoubtedly not restricted to oocytes and the term can be applied to any mRNA which is present in inactive form. (18 Nov 1997) |
| ribosomal RNA | <molecular biology> A nucleic acid found in all living cells. Plays a role in transferring information from DNA to the protein-forming system of the cell. (16 Dec 1997) |
| messenger-like RNA | An ill-defined form of RNA, of high molecular weight, that never leaves the nucleus and is thought to be the precursor of messenger RNA. (05 Mar 2000) |
