Abstract: | CRISPR (clustered regularly interspaced short palindromic repeats) systems were found in the genomes of many eubacteria and the vast majority of archaea. Their unique feature is that CRISPR-mediated immunity is adaptive and can be programmed to protect cells against mobile genetic elements. The review describes the general principles of CRISPR-mediated immunity and characterizes the CRISPR systems of various microorganisms. |
