Molecular scissors, which cut DNA at specific site is
Molecular scissors, which cut DNA at specific site is
Open in App
Solution
The correct option is A Restriction endonuclease
- Restriction enzymes are molecular scissors that cut DNA into pieces. A restriction enzyme (or restriction endonuclease) is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites.
- Ligases join two DNA segments by establishing a new phosphodiester bond between them.
- Cellulase enzymes help in the digestion of starch while pectinase breaks down pectin, a polysaccharide found in plant cell walls.
- Polymerase synthesizes new DNA strands by using parent DNA strands as templates.
So, the correct answer is (A).
