Short pieces of unique sequence in between CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS. These spacers, which are homologous to previously invading viruses, are generated from invading viral DNA and are inserted in between the repeats.

Repetitive nucleic acid sequences that are principal components of the archaeal and bacterial CRISPR-CAS SYSTEMS, which function as adaptive antiviral defense systems.

Regions in the genome that include CRISPR ARRAYS and nearby CRISPR-associated genes, which code for CRISPR-ASSOCIATED PROTEINS.

Regions of archaeal (and bacterial) genomes containing a series of short repeated sequences separated by short unique sequences (CRISPR SPACERS).
