Where this comes from

Abstract

Bacteria and archaea have evolved sophisticated adaptive immune systems that reply on CRISPR loci and a diverse cassette of Cas genes that are classified into three main types and at least eleven subtypes. All CRISPR-Cas immune systems operate through three main stages: acquisition, biogenesis, and interference. This SnapShot summarizes our current knowledge of these fascinating immune systems.
