A Comparative Study of DNA Extraction Method with and without Using Proteinase K Enzyme

Forensic DNA fingerprinting is the most believed method of the criminal investigation. With the advancementin technology, the method has become more and more sensitive and the technology now uses advancedmethod and new generation faster multiplex amplification systems. Most of these improvements in thetechnique are after the extraction of DNA. Despite automation in DNA extraction, still, the basic process oflysis of cells is an integral part of the analysis. We present here the comparison of DNA extraction resultswith and without using the proteinase k enzyme.
