Imagine that it is 1965 and the bacterium Thermus aquaticus has not yet been discovered. As a
geneticist interested in forensics applications, you are attempting to develop a gene-amplifying
technique similar to PCR. In a test tube, you place a DNA sample, free nucleotides, human DNA
polymerase, and the appropriate primers for the DNA sequence being analyzed. You first heat the
sample to 90°C, then cool it to 50°C, and then reheat it to 70°C.
Based on this scenario and your knowledge of how modern PCR works, the result of these
procedures will be
