Q. No.Consider the given two statements:
| Assertion(A): | A piece of DNA, which is somehow transferred into an alien organism, will be able to multiply itself in the progeny cells of the organism. |
| Reason (R): | All DNA molecules are capable of autonomously replicating. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 3. | (A) is True; (R) is False |
| 4. | Both (A) and (R) are False |

Consider the given two statements:
| Assertion(A): | In order to link the alien DNA, the vector must have a large number of recognition sites for the commonly used restriction enzymes. |
| Reason (R): | Presence of one recognition site 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. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 3. | (A) is True; (R) is False |
| 4. | Both (A) and (R) are False |

Ori
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
| I: | is a sequence from where replication starts and any piece of DNA when linked to this sequence can be made to replicate within the host cells. |
| II: | sequence is also responsible for controlling the copy number of the linked DNA. |

Consider the given two statements:
| Assertion (A): | A selectable marker in a plasmid is necessary for identifying recombinant bacteria. |
| Reason (R): | Selectable markers help in the replication of plasmids inside the host bacteria. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
