Detailed explanation-1: -Restriction enzymes are also called “molecular scissors” as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.

Detailed explanation-2: -The correct option is C Restriction endonucleases. Restriction endonucleases are also referred to as molecular scissors. They help scientists cut DNA sequences at a particular point.

Detailed explanation-3: -Restriction enzymes are proteins produced by bacteria to prevent or restrict invasion by foreign DNA. They act as DNA scissors, cutting the foreign DNA into pieces so that it cannot function.

Detailed explanation-4: -Restriction enzymes are called molecular scissors as they cleave DNA at or close to specific recognition sequences known as restriction sites. These enzymes make a single incision on each of the two DNA strands to generate restriction fragments. These enzymes are also called restriction endonucleases.
