... to be analyzed" (Garcia). This results in the detection of all PPV strains. The PCR was then combined with a method called restriction fragment length polymorphism (Garcia). This method uses unique enzymes to identify the DNA fragments, which enables the detection strains of PPV. The variation size of the fragments helps scientists determine which strain of PPV they are looking at. A new gene ... ...
... invariably difficult concepts, such as mutations, were complex and often misunderstood, the general population understood the fundamental idea concluded in his work: I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection. . . .
