Question

Do eukaryotic cells have restriction endonucleases

Answer 1

No, eukaryotic cells do not have restriction endonucleases. ... 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.

Answer 2

Answer:

No, eukaryotic cells do not have restriction endonucleases as the DNA of eukaryotes is highly methylated by methylase – a modification enzyme. This methylation safeguards the DNA from the action of restriction enzymes. In prokaryotic cells, these enzymes are present where they aid in preventing the invasion of DNA by virus.
