The application of DNA (deoxyribonucleic acid) in criminal justice testing is known as forensic DNA analysis. When a culprit commits a crime, then evidence is left at the scene of crime which may contain biological materials with DNA. If the evidence and the latent print match, it may be possible to infer that the person was committed to the crime based on the match. The DNA of a suspect can also be linked to DNA found in blood, semen, saliva, or materials like hair, bone, or skin. Fingerprints can even be used to recover DNA. In the criminal justice system, forensic DNA analysis and DNA profiling are crucial components. Every year, new methods and tools for DNA profiling are developed. Recent developments in nearly all areas of DNA analysis, including sample collection, storage, pre-treatment, DNA extraction, DNA quantification, quality control of DNA testing, and DNA databases, are reviewed in this overview of the literature.
