The pcr (polymerase chain reaction) protocol that is currently used in laboratories was facilitated by the discovery of a bacterium called thermus aquaticus in a hot spring inside yellowstone national park, in wyoming. this organism contains a heat-stable form of dna polymerase known as taq polymerase, which continues to function even after it has been heated to 95°c. a. why would such a heat-stable polymerase be beneficial in pcr? b. what would happen if it weren’t heat stable? c. how might you choose a region of dna for a pcr primer so as to increase the temperature necessary for primer annealing (to minimize nonspecific pcr products)? d. a pcr reaction begins with 5 double stranded segment of dna. estimate the number of double-stranded copies of dna that are present after the completion of 15 amplification cycles?
