I have been asked this question in an interview for internship.

This intriguing question comes from Biotechnology in chapter Biotechnology Principles and Processes of Biology – Class 12

Answer 1

Right choice is (b) pure

The explanation is: The restriction enzyme needs to be in pure form to cut the DNA. The restriction enzymes are molecular scissors that cleave the DNA at specific recognition sites. Restriction enzymes are also known as restriction endonucleases or restrictase.
