Natl. Acad. Sci. USA, online 13 May 2014. "Viral infection and integration is fundamental in the generation of genetic diversity in prokaryotes. After entering an Escherichia coli cell, bacteriophage λ DNA must locate a unique site among ~5 million possible sites on the bacterial genome, with high efficiency and within physiological times, to integrate and establish lysogeny. How does it do it? We show that λ DNA does not carry out an active search. Instead, it remains confined at its entry point where it undergoes limited diffusion, while the process of bacterial DNA replication conveys the bacterial site close to the λ DNA."

Rice study examines how bacteria acquire immunity by Jade Boyd, Rice News & Media Relations, 15 Sep 2010. Bacteria get attacked by viruses called phages, and the CRISPR contain genetic sequences from phages. The CRISPR system is both inheritable and programmable, meaning that some sequences may be there when the organism is first created, and new ones may also be added when new phages attack the organism during its life cycle, says Michael Deem, the John W. Cox Professor in Biochemical and Genetic Engineering.
