Question

DNA fingerprinting method is very useful for
A. DNA tests for identity & relationships
B. Forensic studies
C. Polymorphism
D. All of the above

Answer 1

Hint: DNA profiling is also used for parenthood testing to ascertain eligibility for migration and for genealogical and medical analysis.

Complete Answer:
- DNA fingerprinting is a tool used to distinguish an individual from a DNA sample by analysing specific designs in their DNA. The method of deciding the DNA characteristics of an individual is DNA fingerprinting. The DNA analysis is named as DNA barcoding and is meant to recognise a species rather than an individual.
- DNA fingerprinting is a laboratory procedure used to create a correlation in criminal investigations between biological proof and suspect. A sample of DNA obtained from a crime scene is likened to a suspect's DNA sample.
- The proof came from the perpetrator if the two DNA profiles are matched. In crime investigations, the fingerprint of DNA is a forensic tool that compares the samples of criminal suspects to the details of DNA to measure the risk of involvement in criminal investigations.
- It is also used for parenthood testing to ascertain eligibility for migration and for genealogical and medical analysis. In the areas of botany, agriculture, and zoology DNA profiling has also been used to study the plant and animal populations. DNA fingerprinting is also used in polymorphism.

Thus, the correct answer is D. i.e., All of the above.

Note: DNA fingerprinting is a laboratory procedure used to create a correlation in criminal investigations between biological proof and suspect. A sample of DNA obtained from a crime scene is likened to a suspect's DNA sample. The proof came from the perpetrator if the two DNA profiles are matched.
