crispr-cas9
This page is from my personal notes, and has not been specifically reviewed for public consumption. It might be incomplete, wrong, outdated, or stupid. Caveat lector."Crispr" == "Clustered regularly interspaced palindromic repeats".
These are DNA sequences in bacteria that represent a genetic 'memory' of bacteriophages that attacked its ancestors.
Cas9 is an enzyme that cuts DNA strands that are complementary to the Crispr sequences. It's what assures that the bacterium won't be infected by any of the phages that infected its ancestors.
