Question

interference 8 bacteria CRISPR-Cas is an adaptive defense system in Cas1 exe In the first phase, called bacteriophage DNA is cut into pieces by a complex consisting of Pieces of bacteriophage DNA are inserted into the spacer region of the If the same bacteriophage infects the bacterium a second time, the expression and proteins crispr adaptation begins with production of the pre-crRNA The pre-crRNA consists of several repeat regions separated by base-pairs with the repeat regions and the pre-CrRNA is cut into several each consisting of one repeat region and one spacer CrRNA breaks The tracrRNA acts as a for binding of the tracrRNA crRNA complex to racrRNA In the direct the tracrRNA-CrRNA-Cas9 complex to bind to the phase, the spacer region of the CIRNA acls as a to DNA Cas2 Cas9 is an enzyme that DNA, preventing the bacteriophage from proliferating guide Cas9
