| puff | 1. To blow in puffs, or with short and sudden whiffs. 2. To blow, as an expression of scorn; with at. "It is really to defy Heaven to puff at damnation." (South) 3. To breathe quick and hard, or with puffs, as after violent exertion. "The ass comes back again, puffing and blowing, from the chase." (L' Estrange) 4. To swell with air; to be dilated or inflated. 5. To breathe in a swelling, inflated, or pompous manner; hence, to assume importance. "Then came brave Glory puffing by." (Herbert) Origin: Akin to G. Puffen to pop, buffet, puff, D. Poffen to pop, puffen to blow, Sw. Puffa to push, to cuff, Dan. Puffe to pop, thump. See: Puff. 1. A sudden and single emission of breath from the mouth; hence, any sudden or short blast of wind; a slight gust; a whiff. " To every puff of wind a slave." 2. Anything light and filled with air. Specifically: A puffball. Kind of light pastry. A utensil of the toilet for dusting the skin or hair with powder. 3. An exaggerated or empty expression of praise, especially one in a public journal. Puff adder. <medicine> Any bird of the genus Bucco, or family Bucconidae. They are small birds, usually with dull-coloured and loose plumage, and have twelve tail feathers. See: Barbet . Origin: Akin to G. & Sw. Puff a blow, Dan. Puf, D. Pof; of imitative origin. Cf. Buffet. Source: Websters Dictionary (01 Mar 1998) |

| DNA puff | <molecular biology> An area on a chromosome where transcription of DNA into mRNA, or replication of DNA is occurring, resulting in an enlarged, puffy appearance of the area. Similar to chromosome puff, except generalised to any type of chromosome in any type of organism. (09 Oct 1997) |
| genome, chromosomal | All of the genetic information in the chromosomes of an organism. For humans, that is all of the DNA contained in our normal complement of 46 rod-like chromosomes in virtually every cell in the body. (Mature red blood cells, for one exception, have no nucleus and therefore no chromosomes). The chromosomal genome is synonymous with the nuclear genome. Together with the mitochondrial genome, it constitutes the genome of the human being. (12 Dec 1998) |
| 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. (12 Dec 1998) |
| chromosomal region | That part of a chromosome defined either by anatomical details, notably banding, or by its linkages (linkage group). (05 Mar 2000) |
| chromosomal RNA | RNA associated with the chromosome (not mRNA, tRNA, or rRNA) that may have a role in transcription. (05 Mar 2000) |
