Why we use DNA profiling DNA profiling (also called DNA testing, DNA typing, or genetic fingerprinting) is a technique employed by forensic scientists to assist in the identification of individuals by their respective DNA profiles. DNA profiles are encrypted sets of numbers that reflect a person's DNA makeup, which can also be used as the person's identifier.

Use of DNA finger printing In maternity/paternity testing to prove parentage of a child Forensic science – crime scene investigations to prove innocence or guilt To identify victims of crime or accidents, e.g. death in a fire, to identify human remains etc Evolutionary relationships between living things Identifying viable embryos
