| adhesion structures linked tyrosine kinase | <enzyme> Isolated from mouse embryonic stem cells Registry number: EC 2.7.1.- Synonym: hyk protein (26 Jun 1999) |
|---|---|
| animal structures | Organs and other anatomical structures of non-human vertebrate and invertebrate animals. (12 Dec 1998) |
| mesonephric structures and their fates | <radiology> Male female Tubules Epididymis Mesosalpinx Efferent ductules of testes Ducts Vas deferens Complete involution Seminal vesicles Ejaculatory ducts (12 Dec 1998) |
| complementary structures | Structures that define one another; e.g., the two strands of duplex DNA. (05 Mar 2000) |
| surgically-created structures | Organs or parts of organs surgically formed from nearby tissue to function as substitutes for diseased or surgically removed tissue. (12 Dec 1998) |
| denture-supporting structures | The tissues, teeth, and/or residual ridges, which serve as the foundation for removable partial or complete dentures. (05 Mar 2000) |
| embryonic structures | The anatomical features of the animal embryo deriving from the fertilised ovum, that eventually become the offspring. (12 Dec 1998) |
| genetic | <biology> Pertaining to reproduction or to birth or origin. (07 May 1998) |
| genetic amplification | A process for producing an increase in pertinent genetic material, particularly for increasing the proportion of plasmid DNA to that of bacterial DNA. Includes the production of extrachromosomal copies of the genes for RNA. (05 Mar 2000) |
| genetic assimilation | <genetics> A situation in which a characteristic that is normally expressed only in certain environmental situations becomes fixed in a population so that it no longer requires environmental factors to be expressed. (07 May 1998) |
| genetic association | The occurrence together in a population, more often than can be readily explained by chance, of two or more traits of which at least one is known to be genetic. (05 Mar 2000) |
| genetic block | <biochemistry, molecular biology> An obstruction in a biochemical pathway caused by a mutation that has crippled production of an enzyme critical to the pathway. (07 May 1998) |
| genetic burden | The genetic debt due to harmful mutation but as yet undischarged. (In a large population of fixed size every mutation with diminished genetic fitness will eventually become extinct and depending on the details of inheritance and phenotype must be paid for by a fixed number of genetic deaths per mutation, the genetic debt.) (05 Mar 2000) |
| genetic carrier | An unaffected heterozygote bearing a usually harmful recessive gene, a cancer that bears a dominant but latent age-dependent trait to have offspring with unbalanced karyotypes. (05 Mar 2000) |
| genetic code | <molecular biology> Relationship between the sequence of bases in nucleic acid and the order of amino acids in the polypeptide synthesised from it. A sequence of three nucleic acid bases (a triplet) acts as a codeword (codon) for one amino acid. (18 Nov 1997) |
