Clustered regularly interspaced short palindromic repeat (CRISPR) are essential components of nucleic-acid-based adaptive immune systems that are widespread in bacteria and archaea. Similar to RNA interference (RNAi) pathways in eukaryotes, CRISPR-mediated immune systems rely on small RNAs for sequence-specific detection and silencing of foreign nucleic acids, including viruses and plasmids. However, the mechanism of RNA-based bacterial immunity is distinct from RNAi. Understanding how small…

Efficient In Vivo Genome Editing Using RNA-Guided Nucleases
TLDR
It is shown that the CRISPR-Cas system functions in vivo to induce targeted genetic modifications in zebrafish embryos with efficiencies similar to those obtained using zinc finger nucleases and transcription activator–like effector nucleases.
Unravelling the structural and mechanistic basis of CRISPR–Cas systems
TLDR
This Review summarizes the recent structural and biochemical insights that have been gained for the three major types of CRISPR–Cas systems, which together provide a detailed molecular understanding of the unique and conserved mechanisms of RNA-guided adaptive immunity in bacteria and archaea.

TLDR
Recent progress made in the CRISPR/Cas system is described, which participates in a constant evolutionary battle between phages and bacteria through addition or deletion of spacers in host cells and mutations or deletion in phage genomes.

The structure and function of this newly recognized antiviral mechanism, together with a group of associated proteins, confer resistance to phages, possibly by an RNA-interference-like mechanism.
CRISPR Provides Acquired Resistance Against Viruses in Prokaryotes
TLDR
It is found that, after viral challenge, bacteria integrated new spacers derived from phage genomic sequences, and CRISPR provided resistance against phages, and resistance specificity is determined by spacer-phage sequence similarity.
