Do eukaryotic cells have restriction endonucleases? Justify your answer.

● Eukaryotic cells do not have restriction endonucleases as the DNA of eukaryotes cells is highly methylated by methylase – a modification enzyme. 

● 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 viruses.
