NEET · BiologyEasy
Which enzyme is commonly known as molecular scissors in biotechnology?
- A.DNA ligase
- B.Restriction endonuclease
- C.DNA polymerase
- D.Reverse transcriptase
Show correct answer & step-by-step solution
Correct answer: B — Restriction endonuclease
Solution
- Restriction endonucleases recognize specific DNA sequences.
- They catalyze the cleavage of phosphodiester bonds within the DNA molecule.
- This action allows for the cutting of DNA into fragments.
- Hence the answer is (B).
