Solution

Molecular scissors, which cut DNA at a specific site is Restriction endonuclease.

Explanation:

Restriction enzymes are a type of molecular scissors that cut DNA into smaller bits. A restriction enzyme (or restriction endonuclease) is an enzyme that cuts DNA at or near restriction sites, which are unique recognition nucleotide sequences.

Ligases link two DNA segments together by forming a new phosphodiester bond.
