Bacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell.
Explain why:
1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection
2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infection
Plasmids are important for recombining DNA.
B.) What are the requirments of an expression vector.
A.) There is no change in the DNA sequence if nucleotides are added or removed, it will have no effect to the cell. B.) Mutations in the DNA sequence are all irreversible.
A. Statement A is correct
B. Statement B is correct
C. Both A and B are correct
D. Both A and B are incorrect
