Genome, Mus musculus: All of the genetic information contained in Mus musculus, the laboratory mouse.
The genomes of particular nonhuman organisms such as the mouse have been studied for a number of reasons including the need to improve sequencing and analysis techniques. These nonhuman genomes also provide powerful sets of data against which to compare the human genome.
Almost every human gene has a counterpart in the mouse, with similar DNA sequences and basic functions. If the 23 pairs of human chromosomes were broken into smaller blocks, those pieces could be reassembled to produce a serviceable model of the mouse genome.
The mouse genome has some 3,000 million (3 billion) base pairs and is estimated to have at least 50,000 genes . The sequencing of this genome was completed in March 2000.
The mouse has long been a favorite for biomedical research, including serving as a premiere model organism in genetics.

- Genome, rice
Genome, rice: The first commercially important plant to have its genome sequenced. This feat, completed early in 2001, is particularly important because rice is a staple food for a large portion of the population of the world. With the rice sequence, genes can be located to improve yields and make rice more nutritious. Rice was […]
- Genome, Vibrio cholerae
Genome, Vibrio cholerae: The genome of the bacterium that causes cholera. This genome contains over 4 million bases in its DNA including the sequences for nearly 4,000 genes. The Vibrio cholerae genome is remarkable in that it is arranged in two circular chromosomes. The larger of the two chromosomes has the usual housekeeping genes, similar […]
Genomic: Pertaining to the genome, all of the genetic information possessed by any organism. There are, for instance, the human genome, the elephant genome, the mouse genome, the yeast genome, etc. Humans and many other higher animals have two genomes, namely: A chromosomal genome which is in the nucleus of the cell; and A mitochondrial […]
- Genomic imprinting
Genomic imprinting: The phenomenon of parent-of-origin gene expression. The expression of a gene depends upon the parent who passed on the gene. For instance, two different disorders – Prader-Willi syndrome and Angelman syndrome — are due to deletion of the same part of chromosome 15. When the deletion involves the chromosome 15 that came from […]
