C Correct answer
Explanation

Restriction enzymes are made up of proteins. The main purpose of restriction enzymes is to make new copies of DNA and analyze it. Agarose gel electrophoresis is the main technique which makes use of the restriction enzymes. When the solution containing DNA molecules and restriction enzymes is placed in the gel, an electric current is passed through it which cuts the DNA into fine small fragments.
