| complementary structures | Structures that define one another; e.g., the two strands of duplex DNA. (05 Mar 2000) |
|---|
| 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) |
| 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) |
| RNA, complementary | Synthetic transcripts of a specific DNA molecule or fragment, made by an in vitro transcription system. This crna can be labelled with radioactive uracil and then used as a probe. (12 Dec 1998) |
| complementary | Supplying a defect or helping to do so, making complete, accessory. Origin: L. Complere = to fill (18 Nov 1997) |
| complementary air | The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the tidal volume and the inspiratory reserve volume. Common abbreviation is ic. (12 Dec 1998) |
| complementary base pairing | <molecular biology> The pairing of complementary nucleotide bases (adenine and thymine, guanine and cytosine) to each other via hydrogen bonds from opposite strands of a double stranded nucleic acid (such as DNA or RNA), thereby holding the double-stranded nucleic acid together. (09 Oct 1997) |
| complementary base pairs | <molecular biology> The crucial property of DNA is that the two strands are complementary: Guanine and cytosine are complementary and pair up through their hydrogen bonds, as are adenine and thymine that only form two hydrogen bonds. (adenine and uracil in RNA). (18 Nov 1997) |
| complementary colours | Pairs of different colours of light that produce white light when combined. (05 Mar 2000) |
| complementary DNA | <molecular biology> DNA that is synthesised from a messenger RNA template, the single-stranded form is often used as a probe in physical mapping to locate the gene or can be cloned in the double stranded form. Viral reverse transcriptase can be used to synthesise DNA that is complementary to RNA (for example an isolated mRNA). Acronym: cDNA (13 Nov 1997) |
| complementary DNA cloning | <molecular biology, technique> A lab technique where a double-stranded cDNA molecule (or dscDNA) is inserted into a cloning vector (another DNA molecule which will continue to be capable of replication after insertion of foreign material), so that the gene encoded by the cDNA can be expressed (transcribed and used) or so many copies of the gene can be made. (09 Oct 1997) |
| complementary DNA library | <molecular biology> A collection of all of the mRNA molecules present in a cell or organism, all turned into cDNA molecules with the enzyme reverse transcriptase, then inserted into vectors (other DNA molecules which can continue to replicate after addition of foreign DNA). The library can then be probed for the specific cDNA (and thus mRNA) of interest. (09 Oct 1997) |
