Forensic DNA analysis

DNA double helix

DNA profiling is the determination of a DNA profile for legal and investigative purposes. DNA analysis methods have changed countless times over the years as technology changes and allows for more information to be determined with less starting material. Modern DNA analysis is based on the statistical calculation of the rarity of the produced profile within a population.

While most well known as a tool in forensic investigations, DNA profiling can also be used for non-forensic purposes such as paternity testing and human genealogy research.
