| Assertion (A): | A piece of DNA, if needed to be propagated during recombinant DNA procedures, requires a vector. |
| Reason (R): | The vectors provide the origin of replication. |
| 1. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 2. | (A) is False but (R) is True. |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are True and (R) correctly explains (A). |
| 1. | It recognises a palindromic nucleotide sequence. |
| 2. | It is an endonuclease. |
| 3. | It is isolated from viruses. |
| 4. | it can produce the same kind of sticky ends in different DNA molecules. |
| Assertion (A): | During the heat shock method, the cells are incubated with recombinant DNA at \(42^{\circ} \mathrm{C}\), following by placing them briefly on ice and then putting if back at \(42^{\circ} \mathrm{C}\). |
| Reason (R): | After heat shock, uptake of DNA through transient pores in the bacterial cell wall takes place. |
| 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). |
| 3. | (A) is true but (R) is false. |
| 4. | (A) is false but (R) is true. |
