CRISPRs (clustered regularly interspaced short palindromic repeats) are DNA loci containing short repetitions of base sequences. Each repetition is followed by short segments of spacer DNA from previous exposures to a virus.CRISPRs are found in approximately 40% of sequenced eubacteria genomes and 90% of sequenced archaea.CRISPRs are often associated with cas genes that code for proteins related to CRISPRs.
