Biotechnology and its Applications

In gene therapy of adenosine deaminase (ADA) deficiency, the patient requires periodic infusion of genetically engineered lymphocytes because:

  1. A.Genetically engineered lymphocytes are not immortal cells✓
  2. B.A retroviral vector is introduced into these lymphocytes
  3. C.The gene isolated from marrow cells producing ADA is introduced into cells at embryonic stages
  4. D.Lymphocytes from the patient's blood are grown in culture, outside the body

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
