| chromophore | The part of a visibly coloured molecule responsible for light absorption over a range of wavelengths thus giving rise to the colour. By extension the term may be applied to UV or IR absorbing parts of molecules. Do not confuse with chromatophores. (18 Nov 1997) |
| chromophoric | Chromophorous 1. Relating to a chromophore. 2. Producing or carrying colour; denoting certain microorganisms. (05 Mar 2000) |
| chromophototherapy | Synonym: chromotherapy. Origin: chromo-+ photo-+ G. Therapeia, medical treatment (05 Mar 2000) |
| chromoplast | Plant chromatophore filled with red/orange or yellow carotenoid pigment. Responsible for colour of carrot and of many petals. (18 Nov 1997) |
| chromoplastid | A pigmented plastid, containing chlorophyll, formed in certain protozoans. Origin: chromo-+ G. Plastos, formed, + -id (05 Mar 2000) |
| chromoprotein | One of a group of conjugated proteins, consisting of a combination of pigment (i.e., a coloured prosthetic group) with a protein; e.g., haemoglobin. (05 Mar 2000) |
| chromosomal | Pertaining to chromosomes. (18 Nov 1997) |
| chromosomal aberration | Any abnormality of a chromosome's number or structure. (09 Oct 1997) |
| chromosomal deletion | A microscopically evident loss of part of a chromosome. See: monosomy. (05 Mar 2000) |
| chromosomal gap | A localised area of thinning in a chromatid which may simulate a complete break. (05 Mar 2000) |
| chromosomal instability syndromes | A group of mendelian conditions associated with chromosomal instability and breakage in vitro, they often manifest an increased tendency to certain types of malignancies. See: Bloom's syndrome, fragile X syndrome, xeroderma pigmentosum. (05 Mar 2000) |
| chromosomal map | A formal, stylised representation of the karyotype and of the positioning and ordering on it of those loci that have been localised by any of several mapping methods. (05 Mar 2000) |
| chromosomal mutation | Can refer to any of a number of DNA mutations which results in a change in the protein encoded by the mutated gene, such as point mutations, insertion or deletion mutations (frameshift mutations), or nonsense mutations. More often this refers to mutations involving chromosomes, such as the inversion of part of one chromosome such that the inverted part no longer matches with its homologous pair, a translocation of one part of a chromosome to a different chromosome, deletions of parts of chromosomes, or accidents which happen during the division of the nucleus like the unequal portioning of chromosomes between the daughter cells. (09 Oct 1997) |
| chromosomal proteins, non-histone | Nucleoproteins which in contrast to histones are acid insoluble. They are involved in chromosomal functions; e.g. They bind selectively to DNA, stimulate transcription resulting in tissue-specific RNA synthesis and undergo specific changes in response to various hormones or phytomitogens.

| chromium 51 |
a radioactive isotope of chromium, atomic mass 51, having a half-life of 27.7 days; it decays by electron capture, emitting gamma rays (0.32 MeV), and is used to label red blood cells for measurement of red cell mass or volume, survival time, and sequestration studies, and for the diagnosis of gastrointestinal bleeding, and is used to label platelets to study their survival. It has also been used to label human serum albumin for measurements of gastrointestinal protein loss.
