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 correct but (R) is not correct.
2. (A) is not correct but (R) is correct.
3. Both (A) and (R) are correct and (R) is the correct explanation of (A).
4. Both (A) and (R) are correct 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.
3. Both (A) and (R) are correct and (R) is the correct explanation of (A).
