Consider the given two statements:
| Assertion (A): | In order to link the alien DNA, the vector needs to have very few, preferably single, recognition sites for the commonly used restriction enzymes. |
| Reason (R): | Presence of more than one recognition sites within the vector will generate several fragments, which will complicate the gene cloning. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | (A) is True; (R) is False |
| 3. | (A) is False; (R) is False |
| 4. | Both (A) and (R) are True but (R) does not correctly explain (A). |
