ANSWER KEY DNA Fingerprinting Activity Introduction : DNA fingerprinting relies on the fact that the DNA code is universal for all living things and that there are differences between individuals within that code. Because human DNA is very similar to every other human’s DNA, DNA fingerprinting primarily focuses on the areas of the genetic code that vary greatly amongst individuals. These non- coding regions of DNA, called introns, have the most variable coding sequences within members of a species because they do not code for proteins. Scientists use restri ction enzymes to cut intron segments of DNA. They “run” the fragments of DNA in a gel electrophoresis, and then use the cried bonding patterns (created by the fragments) between individuals to determine identity. Uses for DNA fingerprinting include: crime scene investigation, missing person identification, paternity testing, diagnosing genetic disorders, species identification and many others.
