CRISPR (Clustered Regularly Interspaced Small Palindromic Repeats) and Cas (CRISPR associated) proteins comprise an adaptive immune system in prokaryotes CRISPR Cas systems digest invading nucleic acids and incorporate a 30 bp snippet (“spacer") of the invader into the host genome Spacers are transcribed into CRISPR RNAs (crRNA's) that recognize the same nucleic acid in the event of a repeat invasion and guide nucleases to the target for elimination We hypothesize that a plasmid vector, when transformed into a host cell, could exogenously express a CRISPR/Cas system and prevent the host’s participation in conjugative processes
