Question

rings of Yellowstone National Park. This enzyme is used to copy human DNA from crime scenes. Most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme?View Available Hint(s)Taq polymerase is an enzyme isolated from the organism Thermophilus aquaticus. This organism has been found living in the hot springs of Yellowstone National Park. This enzyme is used to copy human DNA from crime scenes. Most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme?The enzyme will not work on human DNA.Nothing should be altered.The pH should be decreased.The temperature should be raised.

Answer 1

Answer:

The correct option is this: THE TEMPERATURE SHOULD BE RAISED.

Explanation:

The enzyme that is used in Polymerase Chain Reaction (PCR) to copy DNA materials from crime scenes is Taq polymerase. This synthetic enzyme is derived from Thermophilus aquaticus, which is a thermophile bacteria that can tolerate very high temperature.  Because of this characteristic, the enzyme derived from this bacteria can not be used  in the laboratory at room temperature for the purpose of copying DNA. The temperature has to be raised to a very high level, because the enzyme can only be active at very high temperature.
