What are DNA fingerprints and how does the technology work. If you’ve ever seen DNA fingerprints, then what do those seemingly random series of lines on a photographic plate actually mean?
In this video I will explain how DNA fingerprinting works. I’ll look at 2 techniques called Restriction Fragment Length Polymorphism (RFLP) Analysis and Short Tandem Repeat (STR) Analysis.
I’ll also be taking a look at how DNA works and explaining a little of this amazing molecule.
