The dna polymerase used in the polymerase chain reaction (pcr) was initially isolated from the bacterium thermophilus aquaticus that lives in hot springs like old faithful in yellowstone park. now called taq polymerase, this enzyme can be produced synthetically and ordered from a catalog. what best explains why taq polymerase must be used in pcr rather than human dna polymerase?
choose one:
a. human dna polymerase would need to be extracted from humans, which would be unethical.
b. taq polymerase adds dna bases more quickly than human dna polymerase.
c. taq polymerase is much easier to synthesize than human dna polymerase.
d. taq polymerase can withstand the high temperature needed to separate the dna strands.
