Thermocycler is a method that helps in

Options

A. Gene transfer
B. Splicing of DNA
C. Gene cloning
D. Gene isolation

Answer

**Step-by-Step Solution:**

1. **Understanding Thermocycler**: A thermocycler, also known as a thermal cycler, is a laboratory device used in molecular biology.

2. **Function of Thermocycler**: Its primary function is to amplify segments of DNA. This amplification is crucial for various genetic analyses.

3. **Process Involved**: The amplification of DNA is achieved through a process called Polymerase Chain Reaction (PCR). PCR is a widely used technique that allows for the replication of specific DNA sequences.

4. **Applications of PCR**: The PCR process is essential for several applications, including gene cloning, where specific genes are copied for further study or manipulation.

5. **Evaluating Options**: When considering the options provided:
- Option A (gene transfer) is incorrect.
- Option B (splicing of DNA) is also incorrect.
- Option C (gene cloning) is correct.
- Option D (gene isolation) is incorrect.

6. **Conclusion**: Therefore, the correct answer to the question is that the thermocycler helps in **gene cloning**.
