  • a)
    By methylating of bacterial DNA
  • b)
    By methylating of foreign DNA
  • c)
    By phosphorylation of bacterial DNA
  • d)
    By phosphorylation of foreign DNA
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The restriction endonuclease is having a defence mechanism in bacteria...
The bacterial DNA is methylated immediately after replication and this methylated DNA is not a substrate of restriction endonucleases and hence is spared from digestion.
