Answer 1

DNA fingerprints are useful in several areas of society. They are used by professionals in human health and the justice system.Diagnosis of inherited disorders DNA fingerprinting is used to diagnose inherited disorders in both prenatal and newborn babies in hospitals around the world. These
disorders may include cystic fibrosis, hemophilia, Huntington’s disease, familial Alzheimer’s, sickle cell
anemia, thalassemia, and many others.

Early detection of such disorders enables the medical staff to prepare themselves and the parents for proper treatment of the child. In some programs, genetic counselors use
DNA fingerprint information to help prospective parents understand the risk of having an affected child. In other programs, prospective parents use DNA fingerprint information in their decisions concerning affected pregnancies.

Answer 2

DNA fingerprinting is now an essential part of forensics technology. What I mean is, When the police go to a crime scene, they can find some piece of a suspect, like hair or blood. Using this, they can extract the DNA. By breaking the DNA into pieces, and running it through a gel, bands form. Every person has a different version of these bands. (Except identical twins, who are genetic clones.). These bands are called the DNA fingerprint. See this website for more! http://protist.biology.washington.edu/fingerprint/dnaintro.html

I hope this helped!

Answer 3

I'll give an example. Not long before she died, Anna Nicole Smith had a baby. It is not clear whom the father is; several men have claimed paternity. DNA can be extracted from the claimants and compared with the DNA of the baby; the father will have some matching chromosomes. The fingerprinting is done by fractioning the DNA strands at specific sites and comparing the lengths of the fragments using electrophoresis.
