Fingerprints might be left at a crime scene. DNA fingerprinting can establish a criminal's guilt. The majority of a human's DNA will match that of any other human. The sections of DNA used in DNA fingerprinting are passed doen from parents to their children.
DNA fingerprinting, also termed DNA profile analysis is based on the use of the Southern hybridization technique to analyze polymorphic regions of human DNA. Polymorphisms are explained in more detail in problem 5. The experimental steps used in a forensics laboratory for DNA profile analysis are as follows:maller DNA fragments move more rapidly through the pores of the gel matrix than larger DNA fragments. The result is a continuous separation of the DNA fragments according to size, with the smallest DNA fragments moving the greatest distance away from the origin.
