Dear Student

Ans 4. 
The introduction of genetically engineered lymphocyte into an ADA (Adenosine Deaminase) deficiency patient is not a permanent cure as applying this technique for once is not sufficient. The deficiency needs several periodic infusions of such lymphocytes as these cells cannot survive long.

If the gene producing Adenosine Deaminase is isolated from bone marrow and is introduced into the cells of an organism in early embryonic cells, it can be a permanent cure of ADA deficiency.

P.S. For the rest of the questions, kindly post them in a separate thread.
