Its actually pretty neat stuff! Here is a tiny bit more info for ya!
A beginner's guide to DNA fingerprinting basically. The steps are the following-
Extracting the DNA from cells.
Cutting up the DNA using an enzyme.
Separating the DNA fragments on a gel.
Transferring the DNA onto paper.
Adding the radioactive probe.
Setting up the X-ray film.
Yes - we've got the result!
Hope this helped and have a happy day! <3Miss Hawaii
