| genes, overlapping | Genes whose nucleotide sequences overlap to some degree. The overlapped sequences may involve structural or regulatory genes of eukaryotic or prokaryotic cells. (12 Dec 1998) |
|---|---|
| overlapping | <cell biology> In cell locomotion situation in which the leading lamella of one cell moves actively over the dorsal surface of another cell should be distinguished from underlapping. (18 Nov 1997) |
| overlapping gene | <molecular biology> Different genes whose nucleotide coding sequences overlap to some extent. The common nucleotide sequence is read in two or three different reading frames thus specifying different polypeptides. (18 Nov 1997) |
| overlapping reading frame | <molecular biology> Start codons in different reading frames which generate different polypeptides from the same DNA sequence. (09 Oct 1997) |
| palatine tonsil | A large oval mass of lymphoid tissue embedded in the lateral wall of the oral pharynx on either side between the pillars of the fauces. Synonym: tonsilla palatina, tonsilla, faucial tonsil, tonsil. (05 Mar 2000) |
| Gerlach's tonsil | A collection of lymphoid nodules near the pharyngeal opening of the auditory tube. Synonym: tonsilla tubaria, eustachian tonsil, Gerlach's tonsil. (05 Mar 2000) |
| cerebellar tonsil | A rounded lobule on the undersurface of each cerebellar hemisphere, continuous medially with the uvula of the cerebellar vermis. Synonym: tonsilla cerebelli, amygdala cerebelli. (05 Mar 2000) |
| pharyngeal tonsil | A collection of more or less closely aggregated lymphoid nodules on the posterior wall and roof of the nasopharynx, the hypertrophy of which constitutes the morbid condition called adenoids. Synonym: tonsilla pharyngealis, tonsilla adenoidea, Luschka's gland, Luschka's tonsil, third tonsil. (05 Mar 2000) |
| submerged tonsil | A faucial tonsil that is flat and lying below the level of the pillars of the fauces. (05 Mar 2000) |
| third tonsil | A collection of more or less closely aggregated lymphoid nodules on the posterior wall and roof of the nasopharynx, the hypertrophy of which constitutes the morbid condition called adenoids. Synonym: tonsilla pharyngealis, tonsilla adenoidea, Luschka's gland, Luschka's tonsil, third tonsil. (05 Mar 2000) |
| tonsil | <anatomy> One of the two glandular organs situated in the throat at the sides of the fauces. The tonsils are sometimes called the almonds, from their shape. Origin: L. Tonsill, pl., cf. F. Tonsille. Source: Websters Dictionary (01 Mar 1998) |
| tubal tonsil | A collection of lymphoid nodules near the pharyngeal opening of the auditory tube. Synonym: tonsilla tubaria, eustachian tonsil, Gerlach's tonsil. (05 Mar 2000) |
| eustachian tonsil | A collection of lymphoid nodules near the pharyngeal opening of the auditory tube. Synonym: tonsilla tubaria, eustachian tonsil, Gerlach's tonsil. (05 Mar 2000) |
| faucial tonsil | A large oval mass of lymphoid tissue embedded in the lateral wall of the oral pharynx on either side between the pillars of the fauces. Synonym: tonsilla palatina, tonsilla, faucial tonsil, tonsil. (05 Mar 2000) |
| lingual tonsil | A collection of lymphoid follicles on the posterior or pharyngeal portion of the dorsum of the tongue. Synonym: tonsilla lingualis. (05 Mar 2000) |
