Practice questions testing deep understanding of vectors, ADA deficiency, and genetic treatments.
Q1. The first clinical gene therapy was given in 1990 to a 4-year-old girl suffering from ADA (Adenosine Deaminase) deficiency. Why could this specific disease not be permanently cured by a single injection of genetically engineered white blood cells (lymphocytes)?
Q2. Assertion (A): Retroviruses are heavily used as vectors in gene therapy. Reason (R): Retroviruses have the unique natural ability to insert their own genetic material directly into the host cell's DNA. Scientists "disarm" the virus by removing its disease-causing genes and replacing them with the therapeutic human gene.
