| 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) |
| accessory chromosome | A chromosome existing without its normal homologous chromosome; at the reduction division of gametogenesis an accessory chromosome is likely to be included in one daughter cell and not in the other, but may be lost completely by lagging behind on the equatorial plate. Synonym: monosome, odd chromosome, unpaired allosome, unpaired chromosome. (05 Mar 2000) |
| acentric chromosome | A fragment of a chromosome lacking a centromere and unable to attach to the mitotic spindle, therefore unable to take part in the division of a nucleus and randomly distributed in daughter cells. Synonym: acentric fragment. (05 Mar 2000) |
| acrocentric chromosome | A chromosome with the centromere placed very close to one end so that the short arm is very small, often with a satellite. (05 Mar 2000) |
| balanced chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
| B chromosome | <genetics> Small acentric chromosome, part of the normal genome of some races and species of plants. (18 Nov 1997) |
| bivalent chromosome | A pair of chromosome's temporarily united. (05 Mar 2000) |
| male chromosome complement | The large majority of males have a 46, xy chromosome complement (46 chromosomes including an x and a y chromosome). A minority of males have other chromosome constitutions such as 47,xxy (47 chromosomes including two x chromosomes and a y chromosome) and 47,xyy (47 chromosomes including an x and two y chromosomes). (12 Dec 1998) |
| marker chromosome | An abnormal chromosome that is distinctive in appearance but not fully identified. For example, the fragile x chromosome was once called the marker x. (12 Dec 1998) |
