Credit Points 10

Legacy Code 301434

Coordinator Chris Lennard Opens in new window

Description Forensic Analysis of DNA 2 is a continuation of 301148 Forensic Analysis of DNA where students learn about the methods routinely used for the isolation of DNA from cells and techniques applied to DNA quantitation and electrophoretic separation, as well as data analysis, interpretation and reporting. In DNA 2, students learn how to interpret DNA data to include mixture deconvolution and the statistics that apply to DNA matches/inclusions. Modules also guide the student through the basis of Y-STR and Kinship testing statistical applications. Students will also learn the report writing, review and testimony skills required of a DNA analyst. This subject is taught by the University of Florida as part of a collaborative venture with Western Sydney University.
