Nitella [24]
Purpose:Extraction and successful PCR amplification of DNA from humanremains in historical and forensic cases have great importance. The purpose of this study is to demonstrate the efficiency of a method of DNA extraction and PCR amplification of embalmed dried human cadaveric skeletal fragments and teeth specimens from Sokoto, Northwestern Nigeria.
Materials and Methods: The efficiency of a method of DNA extraction and PCR amplification was tested on thirteen (13) embalmed dried human cadaveric skeletal fragments and nine (9) teeth specimens from Sokoto, Northwestern Nigeria were used in the study.
Results: Of the 13 embalmed dried human cadaveric skeletal fragments, 12 (92.3%) samples amplified with apparent bands. For the 9 embalmed dried human teeth specimens, 7 (78%) samples amplified with apparent bands.
<span>Conclusion: The study has shown that our method of DNA extraction and PCR amplification was efficient on embalmed dried human cadaveric skeletal fragments and teeth specimens, from Sokoto, Northwestern Nigeria.</span>

In this method sample from infected area is collected and placed in the center of the slide then a drop of KOH is added on it. After this coverslip is put on the sample and the slide is heated gently to increase the reaction rate of KOH. Then the slide containing fungus is examined under the slide. KOH test is used for both yeast and molds. So the right answer is a.
