PCR is required for:

Options

A. DNA synthesis
B. DNA amplification
C. Protein synthesis
D. Amino acid synthesis

Explanation

**Step-by-Step Text Solution:**

1. **Understanding PCR**: PCR stands for Polymerase Chain Reaction. It is a laboratory technique used to amplify specific DNA sequences.

2. **Purpose of PCR**: The primary requirement for PCR is DNA amplification. This means that PCR is used to create multiple copies of a specific DNA segment.

3. **Components of PCR**: The process involves short DNA sequences known as primers. These primers are essential as they bind to specific regions of the DNA template and initiate the amplification process.

4. **Selection of DNA**: During PCR, the primers are designed to select a particular portion of the genome that needs to be amplified. This targeted amplification is crucial for various applications in molecular biology.

5. **Conclusion**: Therefore, PCR is specifically required for DNA amplification. It is not used for DNA synthesis, protein synthesis, or amino acid synthesis.
