DNA fingerprinting can resolve

Options

A. identification of a person
B. paternity dispute
C. maternity dispute.
D. land dispute

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 particularly useful in various legal and forensic contexts.

2. **Applications of DNA Fingerprinting**:
- **Identification of Individuals**: DNA fingerprinting can be used to confirm the identity of a person. This is crucial in criminal investigations and in verifying personal identities.
- **Paternity and Maternity Disputes**: This technique can resolve disputes regarding parentage. By comparing the DNA of a child with that of potential parents, it can be determined who the biological mother or father is.
- **Forensic Investigations**: In crime scenes, DNA collected from the scene can be matched with suspects to identify the perpetrator. This is a critical application in solving crimes.

3. **Process of DNA Fingerprinting**:
- **DNA Extraction**: The first step involves extracting DNA from the biological sample collected from the crime scene or individuals.
- **PCR Amplification**: The extracted DNA is then amplified using the Polymerase Chain Reaction (PCR) to produce enough DNA for analysis.
- **Gel Electrophoresis**: The amplified DNA is subjected to gel electrophoresis, where it is separated based on size. DNA fragments move towards a positive electrode because DNA is negatively charged.
- **Analysis of DNA Patterns**: After electrophoresis, the DNA fragments are visualized, and patterns are compared. Matching patterns can indicate a biological relationship or link to a crime scene.

4. **Conclusion**: DNA fingerprinting is a powerful tool for resolving identification issues, paternity and maternity disputes, and aiding in criminal investigations. However, it is not typically used for land disputes.
