Unformatted text preview: often used because it is relatively simple and inexpensive. DNA FINGERPRINTING —this is a more complicated test. It is time-consuming and expensive. However, it actually determines the sequence of bases in an organism's DNA and can give much more conclusive proof of relatedness. Restriction enzymes cut a molecule of DNA everywhere a specific base sequence occurs. One specific restriction enzyme would cut DNA everywhere these sequences occur: G ↓ A A T T C or C T T A A G DNA samples from two different organisms are treated separately with the same restriction enzyme. The resulting fragments are separated by electrophoresis, and the number and sizes of the fragments are compared. The more similar the patterns, the more closely related the organisms....
