If you insist that we must evaluate DNA bands in some manner similar to fingerprints, then we must first consider the same three levels of detail that are present in real fingerprints.
Level I: When the DNA band on the plate forms a recurve that passes out or tends to pass out (we are talking about really faint patterns here) on the same side of the electrophoresis plate from which it originated, the band tends to form a loop pattern. If you pulled the electrophoresis plate from a drawer on the left side of your desk, and the flow pattern from the inner most loop area is toward the left side, then it is an ulnar loop... unless of course the box of plates is turned upside down, thus making it a radial loop pattern. If you drop the plate and it causes the looping band to swirl around, it is known as a whorl pattern. If you drop the plate and it breaks, then it's an accidental.
Level II: Where the band ends, is the end of the band (unless it is the Pink Ladies because they never end). Where the band splits from one band into two, it forms a bifurcation. Where one band splits into three, it forms a trifurcation... and into four becomes (what else?) a fournication.
Level III: At this level, you are considering multiple factors, including the shape of the band. If shaped like the Bee Gees, then you are pretty old to even know what shape that is... if shaped like a fuzzy and almost nonexistent band, that could be something associated with Boy George or Ozzy Osboune... if shaped like this, you may be looking at a Scotsman's band.
Alax, kidding aside, please search for DNA information on Google.

After fragments of DNA are seperated by gel electropheresis and they form patterns of bands called a DNA Fingerprint, are those bands the exact ones on our fingers? how can they establish identity? how does it work?
How exactly does DNA "fingerprinting" work? can it establish identity? Are those bands that are formed like the ones on our fingers?

"DNA Fingerprinting" is not fingerprinting at all... to lend credibility to DNA analysis when that science was budding, the wise developers borrowed the term "fingerprinting" to add credibility to their research and also to attempt to explain to folks that it could identify persons with certainty (except for identical twins - monozygotic or identical twins can be differentiated by their fingerprints but not their DNA).

so the DNA Fingerprinting basics are already known. need something more advanced and in-depth(hopefully able to comprehend) or something that isn't already out there in the public
