Approximately 10% of people living in the United States are allergic to penicillin. A research team has developed a new antibiotic that could potentially replace penicillin and treat a wide variety of bacterial infections. To test their theory, the scientists grow Streptococcus pyogenes in petri dishes. S. pyogenes causes numerous infections in humans, like pharyngitis, tonsillitis, and scarlet fever. These diseases are normally treated successfully with penicillin. They expose S. pyogenes to their new strain of antibiotic to determine its effectiveness. What are good positive and negative controls?

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.
