Recent years have seen a steady advancement in technology used to investigate crime scenes. Biological evidence-properly analyzed-can prove a defendant's guilt "beyond a reasonable doubt" or can provide definitive evidence for a suspect's innocence. Most cutting edge techniques now in use for the analysis of forensic biological specimens involve the collection, amplification, and identification of DNA samples from hair, semen, saliva, or blood from either the victim or the perpetrator of a crime. As the tests become more sophisticated, the training required to carry out the analysis becomes more extensive. There are dozens of academic institutions that award a Masters degree in forensic science, including a well-respected program at Michigan State University.

Those interested in forensics can in some cases obtain a job with a Bachelors degree in Cell and Molecular Biology, Chemistry, or Biology. A Masters degree is required for many positions, however, particularly for those interested in advanced DNA analysis.
