Correct option (d) separation of DNA fragments according to their size
Explanation:
When genomic DNA extracted from any tissue of a plant or animal species is digested with a restriction enzyme, it is cleaved into segments. The segments of different sizes can be separated through gel electrophoresis, Gel electrophoresis involves movement of fragments or molecules from a well created on one edge of the gel.
