About this mock
This test covers the foundational concepts of forensic biotechnology with a focus on DNA structure, biological evidence sources, laboratory extraction protocols, quantification methods, and the complete sample-to-profile workflow used in modern casework. It examines understanding of the molecular basis of forensic identification, including the chemical composition of DNA, the role of different biological sample types in criminal and civil investigations, and the practical steps that transform a crime-scene swab into a usable STR profile. The content reflects practices common to accredited forensic laboratories worldwide, drawing on internationally recognised guidelines from bodies such as SWGDAM, the European Network of Forensic Science Institutes, and NIST. No specialist biochemistry background is required. Questions are pitched at the recall and recognition level, making this an ideal starting point for those entering the forensic biology or forensic genomics field.
