Forensic science has been defined simply as the application of science to the law. Forensic science is an umbrella term for many distinct disciplines that may be used in a legal investigation. While forensic science is multidisciplinary, most practitioners work in a particular field, and often a particular specialty in that field.  A laboratory science is a valuable background and analytical chemistry is particularly appropriate. Some knowledge of biochemistry also is useful – e.g., molecular biology, biochemistry and molecular biology laboratory. Courses in forensic science, evidence handling and related topics could be transferred from other schools.
