What questions do you have? Thistechnique uses short sequences of DNA called primers to trigger a chemical reaction that results in theamplification or increase in the concentration number of pieces of a specific region of DNA from asample. They isolated and cultured thenanobacteria in the same way and observed many of the same behaviors. D A partly demineralized nanobacterial group A-D, X Manybacteria can cause diseases.

Assignment for Part V: Scientific results are meaningless if they cannot be repeated and validated. The formation of kidney stones is a good example of this kind ofpathological disease-related form of biomineralization. What are the properties of a biological organism? We are not fanatics, we are scientists. What does the data tell you? This process is also referred to as calcification.
