WebDNA has been used as unique investigation material for forensic purpose since after Alec Jeffrey’s who first introduced restriction fragment length polymorphism (RFLP) in 1985 to identify the unique markers in the genetic material [4]. The method has been improved with the discovery of polymerase chain reaction (PCR) in the mid-1980’s WebWhereas PCR based techniques are rapid in their nature and a small amount of DNA sample required for analysis but there is a chance of contamination during PCR amplification. Non-PCR based technique is RFLP (restriction fragment length polymorphism). This technique firstly used by scientist in the lab during analyzing DNA.
