Question

How DNA finger printing is performed? How could you rule out touch DNA evidence that implicates an individual? Explain each step will reasoning

Answer 1

Dna fingerprinting is laboratoric technique.DNA fingerprinting means unique pattern by DNA fragments.For extracting DNA fingerprints ,First of all we have to Extrac the DNA from cells then Cut the DNA using an enzyme.after that Separate the DNA fragments then
Transfer the DNA into paper and Add the radioactive then
Set up the X-ray film.finally you will get the result.DNA evidence that implicates an individual by,An organism is composed of two different genetically distinct cells from different zygote.Human DNA is 99.9% identical to other persons. There is a 0.1%, it represents millions of different genome where many variation are there.this is 0.1% contributes different health and appearances to the persons. The sequence of the DNA decide where the restriction enzyme cuts, different people will have different pattern of fragments for restriction enzyme. This difference helps to identify people.
