  1. It  was first identified as an adaptive immunity pathway in prokaryotes providing resistance to bacteriophage and analogous to the RNA interference process found in eukaryotes. 
  2. It does not utilize double-stranded sequence-specific breaks and does not  repair using HDR via homologous recombination.
  3. The system consists of two parts, a short synthetic guide RNA ( gRNA) and a nonspecific double-stranded endonuclease termed Cas9. 
  4. It is also possible to program Cas9 with multiple guide RNAs to allow multiplex site-specific editing for designing large deletions, inversions and translocations.
