Description:
The genetic landscape faced by a living cell is constantly changing. Developmental transitions, environmental shifts, and pathogenic invasions lend a dynamic character to both the genome and its activity pattern. A variety of natural mechanisms are utilized by cells adapting to genetic change. These include normal developmental mechanisms and a subset of defense systems for responding to pathogens. At the root of these studies are questions of how a cell can distinguish "self" versus "nonself" and "wanted" versus "unwanted" gene expression.
