Unit description

Introduces students to DNA profiling, its scientific basis and historical development. Students will learn how DNA profiling is performed and explore the philosophical background to the science. Focusing on the Australian context, the unit will examine the use of DNA in court proceedings and study key cases where DNA has been utilised. The unit will also look at how developments may affect future civil and criminal court proceedings and evidence law generally.
