REVIEW from 9.1 Gel electrophoresis is used to separate DNA fragments by size. A DNA sample is cut with restriction enzymes. Electrical current pulls DNA fragments through a gel.

A DNA fingerprint is a type of restriction map. DNA fingerprints are based on parts of an individual’s DNA that can be used for identification. based on noncoding regions of DNA that have repeating DNA sequences number of repeats differs between people

A DNA fingerprint is NOT actually a fingerprint! X X A DNA fingerprint is NOT actually a fingerprint!

DNA fingerprinting is used for identification. DNA fingerprinting depends on the probability of a match. Many people have the same number of repeats in a certain region of DNA. The probability that two people share identical numbers of repeats in several locations is very small. (mother) (child 1) (child 2) (father)

Several regions of DNA are used to make DNA fingerprints. Individual probabilities are multiplied to find the overall probability of two DNA fingerprints randomly matching. 1 1 1 1 500 90 120 5,400,000 1 chance in 5.4 million people to have the same DNA fingerprint x = 1 in every 500 people has 3 copies in location A 1 in every 90 people has 6 copies in location B 1 in every 120 people has 10 copies in location c Several regions of DNA are used to make DNA fingerprints.

DNA fingerprinting is used in several ways. evidence in criminal cases paternity tests (Who da’ Daddy???) immigration requests studying biodiversity tracking genetically modified crops
