What does CRISPR protect bacteria from, and how?
a) CRISPR protects bacteria from viral infections by storing fragments of viral DNA and using them to recognize and destroy viral DNA upon subsequent infections.
b) CRISPR protects bacteria from antibiotic resistance by regulating the expression of antibiotic resistance genes.
c) CRISPR protects bacteria from environmental stressors by enhancing the efficiency of DNA repair mechanisms.
d) CRISPR protects bacteria from oxidative damage by producing antioxidant enzymes.
