DNA technology, one of the most important scientific developments of this century, has entered our daily lives in all fields. Along with the intensive applications in medicine and agriculture, recently the technology has also become indispensable in forensic sciences. Formerly, taking into account that they differ between individuals, blood groups and enzymes were evaluated for personel identification. Nowadays, DNA polymorphism take place of this applications, in consideration of the
advantages in polymorphism rates. After fifty years
of scientific research, today DNA polymorphism is
accepted by the court as one of the most reliable
evidences in crime scene. Although in the
beginning the analysis on DNA polymorphism
requiring high quality of DNA had some technical
limitations, the invention of PCR technology has
overcome this problem and made it possible to
evaluate trace amounts of sample. This
development have increased the importance of the
biological evidences on the crime scene. Today,
DNA molecule derived from a single cell found in a
crime scene can be evaluated and can give a %
99.999 accurate result for the court.
