A bacteriophage, also known informally as a phage, is a virus that infects and replicates within bacteria. The term is derived from Ancient Greek φαγεῖν 'to devour' and bacteria. Bacteriophages are co

CRISPR is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. Each sequence within an individual prokaryotic CRISPR is derived from a DNA fragment of

Simplified diagram of a CRISPR locus. The three major components of a CRISPR locus are shown: cas genes, a leader sequence, and a repeat-spacer array. Repeats are shown as gray boxes and spacers are colored bars. The arrangement of the three components is not always as shown. In addition, several CRISPRs with similar sequences can be present in a single genome, only one of which is associated with cas genes.
