Place the steps in order below using the terms first, second, third, and so on.
Some viral DNA is incorporated into the bacterium's genome as a spacer.
Bacteria is exposed to phage (virus) for the first time and survives.
Cas-9 removes the targeted sequence of cutting it out of the bacterial genome.
The RNA acts as a guide for the protein
Cas-9 finds an exact DNA sequence match
in an invading virus.
Transcription occurs and RNA is made
from DNA.
