Purpose of Gene therapy –
**Core Concept**
The underlying principle being tested is the purpose of **gene therapy**, which involves making targeted changes to a person's genome to treat or cure diseases. **Gene therapy** can be used to replace a faulty gene with a healthy one, inactivate a faulty gene, or introduce a new gene to help fight disease. This concept is crucial in **molecular biology** and **genetics**.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general purpose of **gene therapy**. The primary goal of **gene therapy** is to modify an individual's genes to prevent or treat diseases. This can be achieved by introducing a healthy copy of a defective gene, removing or "knocking out" a faulty gene, or introducing a new gene that helps to fight the disease. **Gene editing** techniques, such as **CRISPR-Cas9**, are often used in **gene therapy**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the correct answer, we cannot determine the incorrect options.
**Option B:**
**Option C:**
**Option D:**
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **gene therapy** can be used to treat both **genetic disorders**, such as **sickle cell anemia**, and **acquired diseases**, such as **cancer**. **Gene therapy** has the potential to revolutionize the treatment of many diseases.
