Why is Taq polymerase required to perform a polymerase chain reaction (PCR)?
A. Taq polymerase is heat stable and can therefore withstand the high temperature steps required of PCR that most other enzymes cannot tolerate.
B. Taq polymerase is more efficient than other polymerases.
C. Taq polymerase is pressure stable and can therefore withstand the high pressure steps required of PCR that most other enzymes cannot tolerate.
D. Taq polymerase makes fewer errors than other polymerases.
E. All of the choices are correct.

. Imagine that you have been bitten by a poisonous snake with neurotoxic venom. Thankfully, you are rushed to the emergency room of a local hospital, where you receive antivenom. Your condition subsequently returns to normal. Before your release, your physician chastises you for not being more careful. He informs you that you were within minutes of not being able to breathe as the result of the venom's effect on the nervous control of your breathing. As a biology student, you consider this carefully, and hypothesize that your breathing would have stopped because the venom would cause
A. your trachea to collapse. B. your lungs to collapse. C. your diaphragm to become inactive. D. your blood to lose oxygen.
