| genome projects | Research and technology development efforts aimed at mapping and sequencing some or all of the genome of human beings and other organisms. (05 Mar 2000) |
| genome, bacterial | The complete gene complement contained in a single chromosome in a bacterium. (12 Dec 1998) |
| 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) |
| genome, fungal | The complete gene complement contained in a set of chromosomes in a fungus. (12 Dec 1998) |
| genome, human | All of the genetic information, the entire genetic complement, all of the DNA in a person. Humanity's DNA is the treasury of human inheritance. It is this extraordinary repository of genetic information which the Human Genome Project in the United States and comparable programs in other countries around the world that belong to HUGO (the HUman Genome Organisation) are designed to fully fathom. (12 Dec 1998) |
| genome, mitochondrial | The genetic information contained in the circular chromosome of the mitochondrion, a structure located outside the nucleus in the cytoplasm of the cell. The mitochondrial genome and the chromosomal (nuclear) genome together constitute the entire genome. (12 Dec 1998) |
| genome, plant | The complete gene complement contained in a set of chromosomes in a plant. (12 Dec 1998) |
| genome, protozoan | The complete gene complement contained in a set of chromosomes in a protozoan. (12 Dec 1998) |
| genome, viral | The complete gene complement contained in a DNA or RNA molecule in a virus. (12 Dec 1998) |
| 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.
