Chromosome Structure and Transposable Elements

The house mouse, Mus musculus, is one of the oldest and most important organisms used for genetic studies. Molecular techniques allow genes to be introduced into mice on yeast artificial chromosomes (YACs). Pigment in the brown mice is produced by a gene for tyrosinase that is carried on a YAC. The white mouse is a littermate, without the introduced gene. (Carolyn A. McKeone/Photo Researchers.)
