Since it was first introduced into forensic science in the mid-1980s, DNA profiling has evolved into one of the most powerful tools in the forensic armoury and hence in the investigation and solving of crimes.

In this time the techniques of DNA profiling have changed enormously, and their sensitivity is such that DNA profiling can now identify DNA sources from as little as 6–10 human cells. Typical sources of DNA in a forensic investigation have grown from large stains of body fluids, to microscopic traces of skin.

This subject examines the chemical, immunological and molecular biological techniques necessary to locate and identify biological materials and their origin on a variety of crime scene items, and to extract, purify and analyse DNA from these items. DNA extraction, amplification and examination using standard technologies is highlighted, as required for court admissible evidence.

Population genetics and population structure are addressed in relation to relevance and the probative weight of results. Also discussed are the future trends in forensic DNA analysis, and other applications of molecular biology to forensic analyses.
