Buffers Keeps the Balance Lab 4. Which phosphate buffer solution in Part B corresponds to the composition of an ideal buffer solution? Compare its measured pH value with the calculated pH of the ideal buffer solution.
5. Use the universal indicator color chart to compare the observed pH changes for phosphate buffers A and B and the control solution (water) upon addition of HCI and NaOH. Were phosphate buffers A and B equally effective in resisting pH changes upon addition of either HCI or NaOH?
6. Do the results in Data Tables 2 and 3 confirm that the ideal buffer is optimally effective upon addition of either HC) or CHO N

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.
