Q44 / 180 · NEET 2026 (Re-NEET) · Botany
Match List-I with List-II.
List-I List-II A. Transformation I. Restriction enzyme B. Cloning site II. Transfer DNA to host bacteria C. Selection III. Replication D. Ori IV. Antibiotic
Choose the correct answer from the options given below :
| List-I | List-II |
|---|---|
| A. Transformation | I. Restriction enzyme |
| B. Cloning site | II. Transfer DNA to host bacteria |
| C. Selection | III. Replication |
| D. Ori | IV. Antibiotic |
- AA-IV, B-I, C-III, D-II
- Correct answerBA-II, B-I, C-IV, D-III
- CA-I, B-II, C-IV, D-III
- DA-III, B-IV, C-II, D-I
Solution
Transformation is a procedure through which a piece of DNA is introduced into a host bacterium. Thus, A matches with II.
Cloning sites are the recognition sites for restriction enzymes where the alien DNA is linked to the vector. Thus, B matches with I.
Selection of transformants from non-transformants is facilitated by selectable markers, which are typically genes encoding resistance to specific antibiotics. Thus, C matches with IV.
Ori (origin of replication) is the specific DNA sequence responsible for initiating replication. Thus, D matches with III.
The correct matching is A-II, B-I, C-IV, D-III.
Answer: A-II, B-I, C-IV, D-III
Cloning sites are the recognition sites for restriction enzymes where the alien DNA is linked to the vector. Thus, B matches with I.
Selection of transformants from non-transformants is facilitated by selectable markers, which are typically genes encoding resistance to specific antibiotics. Thus, C matches with IV.
Ori (origin of replication) is the specific DNA sequence responsible for initiating replication. Thus, D matches with III.
The correct matching is A-II, B-I, C-IV, D-III.
Answer: A-II, B-I, C-IV, D-III
Hence, the correct answer is option: 'B'.
