   How does forensic DNA analysis work?

   • To perform a forensic DNA analysis, DNA is first extracted from a sample. Just one nanogram of DNA is usually a sufficient quantity to provide good data. The region containing each STR is then PCR amplified and resolved according to size, giving an overall profile of STR sizes (alleles).

   What does DNA mean in forensics?

   • In forensics, using DNA means comparing a profile from a sample to a reference profile, such as taken from a witness, persons of interest, or criminal DNA databases. By itself, a DNA profile is a set of numbers. The only thing we can figure out is whether the owner of the DNA has a Y-chromosome – that is, their biological sex is male.

   Why is DNA forensic technology important?

   • Further public awareness of the power of DNA forensic technology will help lawmakers decide these issues in a way that seeks to strike a balance between protecting individuals' genetic privacy and protecting innocent citizens from crime. DNA evidence is easy to obtain because genetic material is found in all human cells, save red blood cells.

   How did forensic genetics work?

   • Together with the discovery by Mullis in 1983 of the polymerase chain reaction (PCR), Sir Alec Jeffreys in the field of forensic genetics used this technique by studying a set of DNA fragments that proved to have unique characteristics, which were nonrecurring and intrinsic for each individual, the only exception being identical twins.
