Which of the following is not required for any of the techniques of DNA fingerprinting available at present ?

Options

A. Zinc finger analysis
B. Restriction enzymes
C. DNA-DNA hybridization
D. Polymerase chain reaction

Explanation

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which option is not required for any of the techniques of DNA fingerprinting currently available.

2. **Identify Techniques of DNA Fingerprinting**: Familiarize yourself with the common techniques used in DNA fingerprinting. These include:
- Polymerase Chain Reaction (PCR)
- Gel Electrophoresis
- Restriction Fragment Length Polymorphism (RFLP)
- DNA Hybridization

3. **Analyze Each Technique**:
- **PCR**: This technique is essential for amplifying DNA samples, making it easier to analyze.
- **Gel Electrophoresis**: This is used to separate DNA fragments based on their size.
- **RFLP**: This involves digesting DNA with restriction enzymes and is crucial for analyzing variations in DNA sequences.
- **DNA Hybridization**: This technique is used to identify specific sequences within the DNA.

4. **Evaluate the Options**: Look at the options provided (not specified here, but inferred from the context):
- Identify which of the options are related to DNA fingerprinting techniques and which are not.

5. **Identify the Incorrect Option**: From the context of the video, zinc finger analysis is mentioned as a technique used for protein testing, not for DNA fingerprinting. Therefore, it is the option that is not required for any DNA fingerprinting techniques.

6. **Conclusion**: The answer to the question is that zinc finger analysis is not required for any of the techniques of DNA fingerprinting.

**Final Answer**: Zinc finger analysis (Option 1) is not required for any of the techniques of DNA fingerprinting available at present.
