DNA | What is DNA? | Someone was arrested first time in History with the help of DNA

First time in the History, someone was being sentenced by the decision of the genetic fingerprint. in 1983 a 15-years old girl was murdered after sexually abused in a village near Leicester University. 3 years later, again a 15-year old girl was murdered after sexual abuse. A team of investigation officer took help from Dr.Alec Jeffreys who introduce genetic fingerprint for the first time. they took DNA from both corpses & found Both murders have done by the same person. Based on this evidence, the Law enforcement agency determined a tremendous test because the murderer's blood group was A, & positive for Enzyme gpa1. Therefore, they took blood approx 4000+ man from the nearest town, only 10% people were resulted positive, A man didn't give blood & manipulate to his friend for his replacement. Some after months, Police got to know all these things and the offender was arrested. Enzyme gpa1 positive was found in offender's blood, the doctor found exact resemblance in both DNA which was taken on the bodies. 
This is how someone was arrested first time with the help of DNA...

DNA

Have you ever think that why do you look like your parents, why your hair colour is black or golden, and how criminal being caught with the help of DNA. Genetics can answer all these questions.
you will be surprised by the fact of human DNA. that, all the data in the world can be stored in a DNA Spoon size drive.

The human body has infinite cells. Every cell contains a molecule, known as "DNA" (DeoxyriboNucleic Acid). which consists of two chromosomes, in it, there is isolation speciality of a person, such as, our eye colour, skin tone, & the habits we get from our parents. DNA explains everything about life, history & identity of a person. Any unknown person can be identified with the help of this test. tester's need sample of a person's blood, bone, hair this might be another part of a person, because, blood circulates all over the body, a DNA test can be done with fingerprints also. 

How They Make It Happen

The work of research officer keeps a great importance, DNA samples are taken precautionary from the blood In Biological Lab, Computerized results are obtained from them... Which is called the DNA profile, this test might be taken a week.
