The polymerase chain reaction (PCR) is a powerful technique

Options

A. mutase genes
B. amplify genes
C. inhibit DNA synthesis
D. induce protein synthesis

Answer

**Step-by-Step Solution:**

1. **Understanding PCR**: The Polymerase Chain Reaction (PCR) is a technique used to amplify specific segments of DNA. It allows researchers to create millions of copies of a particular DNA sequence in a short period.

2. **Analyzing the Options**:
- **Option A: It mutates genes**: This is incorrect. PCR does not mutate genes; it simply amplifies the existing DNA.
- **Option B: It amplifies genes**: This is correct. PCR is specifically designed to amplify a targeted DNA sequence.
- **Option C: It inhibits DNA synthesis**: This is also incorrect. PCR promotes DNA synthesis by creating copies of the target DNA.
- **Option D: It induces protein synthesis**: This option is incorrect as well. PCR does not directly involve protein synthesis; it focuses on DNA amplification.

3. **Conclusion**: After analyzing all the options, the only correct statement about PCR is that it amplifies genes. Therefore, the correct answer is **Option B**.
