In gene therapy of Adenosine Deaminase (ADA) deficiency, the patient requires periodic infusion of genetically engineered lymphocytes because:
| 1. | Genetically engineered lymphocytes are not immortal cells. |
| 2. | Retroviral vector is introduced into these lymphocytes. |
| 3. | Gene isolated from marrow cells producing ADA is introduced into cells at embryonic stages |
| 4. | Lymphocytes from patient's blood are grown in culture, outside the body. |

Give below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
| Assertion (A): | In human beings, insulin is synthesized as a pro-hormone which needs to be processed before it becomes fully mature and functional. |
| Reason (R): | The extra stretch of C-peptide is to be removed from A and B peptide chain of insulin. |
In the light of the above statements, Choose the most appropriate answer from the option given below :
| 1. | (A) is True but (R) is False. |
| 2. | (A) is False but (R) is True. |
| 3. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 4. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R).
| Assertion (A): | The nematode cannot survive in a transgenic host which expresses specific interfering RNA. |
| Reason (R): | Nematode-specific gene introduced in the host produces both sense and antisense complementary RNA which initiate RNA interference in the host cell. |
In light of the above statement, choose the most appropriate answer from the option given below :
| 1. | (A) is correct but (R) is not correct. |
| 2. | (A) is not correct but (R) is correct. |
