Which of the following techniques is useful in forensic science ?

Options

A. Genectic imprinting
B. DNA footprinting
C. DNA fingerprinting
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Forensic Science**: Forensic science involves the application of scientific methods and techniques to investigate crimes and identify individuals involved in criminal activities.

2. **Identifying Techniques Used in Forensic Science**: Various techniques can be employed in forensic science, but the focus is on those that are particularly effective for individual identification.

3. **Importance of DNA in Forensic Science**: DNA contains unique genetic information for each individual (except identical twins). This uniqueness makes DNA a powerful tool for identifying individuals.

4. **DNA Fingerprinting**: One of the most significant techniques used in forensic science is DNA fingerprinting. This method allows forensic scientists to compare DNA samples from a crime scene with DNA samples from potential suspects.

5. **Comparing DNA Samples**: In a forensic investigation, DNA samples collected from a crime scene (such as blood, hair, or skin cells) can be compared to DNA samples from suspects to determine if there is a match.

6. **Eliminating Incorrect Options**: The question presents various techniques, including genetic imprinting and DNA footprinting. It is essential to recognize that these terms are not standard techniques used in forensic science. The correct term is DNA fingerprinting.

7. **Conclusion**: Based on the analysis, the technique that is most useful in forensic science for individual identification is DNA fingerprinting.

**Final Answer**: The technique useful in forensic science is DNA fingerprinting.
