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
