Transgenic Mice. One of the simplest ways to study gene function in a mouse is exogenous expression of a protein in some or all tissues. For this type of genetic modification, a new piece of DNA is introduced into the mouse genome.ne of the simplest ways to study gene function in a mouse is exogenous expression of a protein in some or all tissues.

A knockout mouse or knock-out mouse is a genetically modified mouse (Mus musculus) which researchers have inactivated, or knocked out, an existing gene by replacing it or disrupting it with an artificial piece of DNA.hile knockout mouse technology represents a valuable research tool, some important limitations exist. About 15 percent of gene knockouts are developmentally lethal, which means that the genetically altered embryos cannot grow into adult mice.
