Homing endonucleases: DNA scissors on a mission.

Abstract excerpt

Buried within the genomes of many microorganisms are genetic elements that encode rare-cutting homing endonucleases that assist in the mobility of the elements that encode them, such as the self-splicing group I and II introns and in some cases inteins. There are several different families of homing endonucleases and their ability to initiate and target specific sequences for lateral transfers makes them...
