Three known positive clinical samples were subjected to three different procedures of DNA extraction. The DNA template obtained by boiling method showed smearing on the agarose gel electrophoresis. The modified phenol-chloroform method of DNA extraction yielded good quantity of DNA than the commercial DNA extraction kit. The purity of the extracted DNA by both the modified phenol-chloroform method and commercial DNA extraction kit method was found to be almost equal. Thus the modified phenol-chloroform method although time consuming was found to be simple and inexpensive and could be employed for large number of samples. Whereas the expensive commercial DNA extraction kit method could be employed when results are required within a day.enArticle
