Solution

The correct option is C

Restriction endonuclease


Restriction endonuclease enzymes are called as the 'genetic scissors' since they are used to cut the DNA strands at specific positions. These enzymes are of immense importance in genetic engineering.

Protein digesting enzymes are called as proteases, lipid/fat-digesting enzymes are called as lipases. Ligase is the enzyme that seals the gaps in the DNA strand created by restriction endonucleases.
