A forensic scientist obtains a carpet sample from a crime scene that contains a very small amount of DNA. The scientist needs to determine rapidly if the DNA belongs to a dangerous animal believed to be responsible for a death. Only the presence of one specific gene will tell her if it is the particular animal. Which of the following techniques would help her accomplish this task? A.
gene cloning
B.
PCR
C.
RLFPs
D.
Southern blotting
E.
genome mapping

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? 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.
