Question

What forms the basis of DNA fingerprinting?

Answer 1

DNA fingerprinting:

1. DNA fingerprinting is a technique that shows the genetic makeup of living things.
2. It is a method of finding the difference between the satellite DNA regions in the genome.
3. DNA fingerprinting was invented by Professor Sir Alec Jeffery in the year 1984.
4. He was widely considered the father of DNA fingerprinting.
5. The basis of DNA fingerprinting is VNTR.
6. VNTR is a satellite DNA as a probe showing a high degree of polymorphism.
7. This implies that there are repetitive sequences of DNA that are found across individuals of all species.
8. Scientists identify variations in these sequences.
9. These variations are unique and give rise to unique DNA prints.
10. DNA fingerprinting involves identifying repetitive DNA.
11. And the repetitive DNA is separated from the bulk genomic DNA.
12. Bulk DNA forms major peaks and other DNA forms small peaks called satellite DNA.
13. DNA fingerprinting can be used for crime investigations as well as paternity disputes.
