Q22 ⇒ What is the normal role of restriction endonucleases in bacterial cells? To degrade invading phage DNA [other wrong options] [Discuss in forum] To degrade the bacterial chromosome into small pieces during replication To produce RNA primers for replication All of the above |
Q23 ⇒ Bacterial cells protect their own DNA from degradation by restriction endonucleases by methylating the DNA at the sites that the enzyme recognizes [other wrong options] [Discuss in forum] deleting all recognition sites from the genome not producing any restriction endonucleases having anti restriction endonucleases |
