| genomic | Relating to a genome. (05 Mar 2000) |
|---|---|
| genomic DNA | <molecular biology> The DNA which is found in the organisms genome and is passed on to offspring as information necessary for survival. The phrase is used to distinguish between other types of DNA, such as found within plasmids. (09 Oct 1997) |
| genomic formula | <molecular biology> The method used to identify the number of sets of chromosomes within a cell or organism (i.e. Its ploidy). Each set is designated n so one set is n is haploid, two sets is 2n is diploid, three sets is 3n is triploid, four sets is 4n is tetraploid, etc. Also, 2n+1 is known as trisomy (i.e. Two full sets plus a third copy of one of the chromosomes). (09 Oct 1997) |
| genomic imprinting | <genetics, molecular biology> Parent specific expression or repression of genes or chromosomes in offspring. There are an increasing number of recognised chromosomal imprinting events in pathological conditions: for example preferential transmission of paternal or maternal predisposition to diabetes or atopy, preferential retention of paternal alleles in rhabdomyosarcoma, osteosarcoma, retinoblastoma and Wilm's tumour, preferential translocation to the paternal chromosome 9 of a portion of maternal chromosome 22 to form the Philadelphia chromosome of chronic myeloid leukaemia. (18 Nov 1997) |
| genomic library | <molecular biology> A collection of DNA molecules, derived from restriction fragments that have been cloned in vectors, that includes all or part of the genetic material of an organism. (18 Nov 1997) |
| library, genomic | A collection of DNA clones made from a set of randomly generated overlapping DNA fragments representing the entire genome of an organism. As a molecular genetic sequel to john steinbeck's of mice and men , today you can have a mouse genomic library or a human genomic library. (12 Dec 1998) |
