In the CRISPR-Cas System,which Component is Responsible for Phage Recognition

Question

In the CRISPR-Cas system,which component is responsible for phage recognition?
A)Pre-cRNA transcript
B)cRNA subunits
C)Cas helicase
D)Cas nuclease
E)CRISPR locus

Accepted Answer

cRNA subunits are responsible for recognizing the DNA of invading phages in the CRISPR-Cas system. They guide the Cas nuclease to the target DNA sequence for cleavage.
