What is the purpose of woolite when extracting DNA?
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>

List four uses of lactic acid fermentation. List four uses of alcoholic fermentation.
Volgvan

Answer:

The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. Two of the most common applications of lactic acid fermentation are in the production of yogurt and sauerkraut.

Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.
