Bacteria have an immune system based on gene sequences. Take over cell with dna, control the proteins that are created. Spacer region is incorporated into an array, added to genetic makeup so host will remember the virus has infected it. Host dna starts expressing gene to make enzyme (scissors) When the same virus returns, the host can recognize the sequence and clip it. Can be used by doctors in human genes. Memories are not carried forever, only recent infections. Associations reflect frequency and cooccurrence of elements in the environment.
