What does the CRISPR array consist of?

• Spacer DNA and palindromic repeats

• Viral proteins

• Only spacer DNA

• Only palindromic repeats

How does the CRISPR-Cas9 system recognize and respond to repeated viral infections?

• By producing antibodies

• By transcribing and translating Cas proteins

• By mutating its own DNA

• By releasing toxins

What is the role of the guide RNA in the modified CRISPR-Cas9 system?

• To cut the DNA
