Correction genetic defect involves delivery of a …… gene into the individual or embryo to take over the function of and compensate for the …… gene

Options

A. functional : healthy
B. defective : functional
C. normal : non-fuctional
D. non-functional : normal

Answer

To solve the question regarding the correction of genetic defects, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Genetic Defects**: Genetic defects often arise from mutations in specific genes that lead to hereditary diseases. These mutations can render the gene non-functional.

2. **Concept of Gene Therapy**: Gene therapy is a technique used to treat or prevent diseases by directly altering the genes inside a person's cells. It involves the delivery of a functional gene to replace or compensate for a defective or non-functional gene.

3. **Identifying the Genes**: In the context of the question, we need to identify two types of genes:
- The **normal gene** that will be delivered to the individual or embryo.
- The **non-functional gene** that is being compensated for.

4. **Formulating the Answer**: Therefore, the correction of a genetic defect involves the delivery of a **normal gene** into the individual or embryo to take over the function of and compensate for the **non-functional gene**.

5. **Final Answer**: The completed sentence would read: "Correction of genetic defect involves delivery of a **normal** gene into the individual or embryo to take over the function of and compensate for the **non-functional** gene."
