Question

What make a DNA fingerprint unique?

Answer 1

DNA fingerprint:

1. DNA fingerprinting is a laboratory technique that determines the genetic makeup of living organisms.
2. This technique detects minisatellites present in the genome and creates a pattern that is unique to an individual.
3. Minisatellites are short, repetitive sequences that are 10-60 base pairs long.
4. These regions contain high amounts of variation.
5. The sequence of DNA on each of the chromosomes makes a DNA fingerprint unique to each individual, except for identical twins.
6. This technique is employed in paternity tests and forensics.
