Do eukaryotic cells have restriction end | Class 12 Biology Chapter Biotechnology Principles and Process, Biotechnology Principles and Process NCERT Solutions

Question: Do eukaryotic cells have restriction endonucleases? Justify your answer.

Answer:

No, eukaryotic cells do not have restriction endonucleases. This is because the DNA of eukaryotes is highly methylated by a modification enzyme, called methylase. Methylation protects the DNA from the activity of restriction enzymes .These enzymes are present in prokaryotic cells where they help prevent the invasion of DNA by virus.
