Viral Diversity Threshold for Adaptive Immunity in Prokaryotes [PDF]
mBio, 2012 Bacteria and archaea face continual onslaughts of rapidly diversifying viruses and plasmids. Many prokaryotes maintain adaptive immune systems known as clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated genes (Cas ...

CRISPR-Cas Systems in Prokaryotes [PDF]
Polish Journal of Microbiology, 2015 Prokaryotic organisms possess numerous strategies that enable survival in hostile conditions. Among others, these conditions include the invasion of foreign nucleic acids such as bacteriophages and plasmids. The clustered regularly interspaced palindromic repeats-CRISPR-associated proteins (CRISPR-Cas) system provides the majority of bacteria and ...
