The method of DNA fingerprinting involves the use of :

Options

A. Restrication enzymes
B. Taq polymerase
C. Oligonucleotide primers
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding DNA Fingerprinting**: DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It is commonly used in forensic science, paternity testing, and genetic research.

2. **Identifying the Components Used**: The question asks about the methods involved in DNA fingerprinting. The options provided are:
- A) Restriction enzymes
- B) Taq polymerase
- C) Oligonucleotide primers
- D) All of the above

3. **Analyzing Each Option**:
- **Restriction Enzymes**: These enzymes are crucial in DNA fingerprinting as they cut DNA at specific sequences, allowing for the isolation of DNA fragments that can be analyzed.
- **Taq Polymerase**: This enzyme is primarily used in the Polymerase Chain Reaction (PCR) to amplify DNA. While PCR can be part of the DNA fingerprinting process, Taq polymerase itself is not directly involved in the fingerprinting method.
- **Oligonucleotide Primers**: These are short sequences of nucleotides that are used in PCR to initiate the DNA synthesis process. Similar to Taq polymerase, they are not a direct component of DNA fingerprinting but are used in PCR.

4. **Determining the Correct Answer**: Since restriction enzymes are directly involved in the DNA fingerprinting process, while Taq polymerase and oligonucleotide primers are more relevant to PCR, the correct answer is:
- **A) Restriction Enzymes**

5. **Final Answer**: The method of DNA fingerprinting involves the use of restriction enzymes.
