Question

Which of the following is NOT a challenge in gene therapy?

• A. Immune response
• B. Targeted delivery
• C. Ethical concerns
• D. PCR amplification

Hint:

Major challenges in gene therapy: \[ \boxed{ \text{Immune response, targeted delivery, vector safety and ethical concerns} } \]

Answer 1

The Correct Option is D

Step 1: Recall the major challenges in gene therapy. Gene therapy faces several challenges, including: \[ \boxed{ \begin{aligned} &\text{Immune response against vectors} &\text{Targeted delivery of therapeutic genes} &\text{Ethical and safety concerns} \end{aligned} } \]

Step 2: Identify the option that is not a challenge. PCR amplification is a laboratory technique used to amplify DNA and is not considered a challenge in gene therapy. Therefore, \[ \boxed{(D)} \] is the correct answer.
