| complementary sequence | <molecular biology> Nucleicacid base sequences that can form a double-stranded structure bymatching base pairs, the complementary sequence to G-T-A-C is C-A-T-G. (09 Oct 1997) |
|---|---|
| complementary strand | See: replicative form. (05 Mar 2000) |
| complementary strands | <molecular biology> Two single strands of DNA in which the nucleotide sequence is such that they will bind as a result of base pairing throughout their full length. (05 Jan 1998) |
| complementary structures | Structures that define one another; e.g., the two strands of duplex DNA. (05 Mar 2000) |
| complementation | <cell biology> The ability of a mutant chromosome to restore normal function to a cell that has a mutation in the homologous chromosome when a hybrid or heterokaryon is formed the explanation being that the mutations are in different cistrons and between the two a complete set of normal information is present. (18 Nov 1997) |
| complementation-fixation test | <investigation> A test for the presence of antibodies in a serum, based on whether an antigen and complement, when put together with some red blood cells, are able to destroy them. If the red blood cells are destroyed, then antibodies were not present to prevent it. If the red blood cells are not destroyed, then antibodies were present to combine with the antigen and bind the complement, making them unable to attack the red blood cells. (09 Oct 1997) |
| complete A-V block | complete atrioventricular dissociation, complete A-V dissociation |
| complete abortion | The complete expulsion or extraction from its mother of a foetus or embryo, complete expulsion of any other product of gestation. (e.g., hydatidiform mole). (05 Mar 2000) |
| complete achromatopsia | Achromatopsia with absent colour vision, nystagmus, reduced visual acuity, and light aversion. Synonym: rod monochromatism, typical achromatopsia. (05 Mar 2000) |
| complete antibody | An antibody which causes agglutination of erythrocytes when they are suspended either in saline or in a protein medium. (05 Mar 2000) |
| complete antigen | Any antigen capable of stimulating the formation of antibody with which it reacts in vivo or in vitro, as distinguished from incomplete antigen (hapten). (05 Mar 2000) |
| complete ascertainment | Method by which all families with at least one affected individual in a population are certain or have an equal chance of being identified by survey or an appropriate random sampling technique. (05 Mar 2000) |
| complete atrioventricular dissociation | A-V dissociation not interrupted by ventricular captures. Synonym: complete A-V block. (05 Mar 2000) |
| complete blood count | <haematology, investigation> The number of red blood cells, white blood cells and platelets are present in the patients sample of blood is determined. most common test done on the blood. Acronym: CBC Synonym: full blood count. (16 Mar 1998) |
| complete cataract | A cataract in which both the nucleus and cortex are opaque. Synonym: complete cataract, ripe cataract. (05 Mar 2000) |
