The best place to look for a new, heat-tolerant DNA polymerase enzyme would be among the
A) acidophilic thermophiles.
B) methanogens.
C) strict halophiles.
D) proteobacteria.
E) cyanobacteria.

Question

Quizplus · Accepted Answer

Acidophilic thermophiles are microorganisms that thrive in acidic environments and high temperatures. Therefore, they are more likely to have heat-tolerant enzymes, including DNA polymerases. Acidophilic thermophiles are often found in geothermal areas such as hot springs and volcanoes, where the temperature can reach up to 80°C. Therefore, searching for a heat-tolerant DNA polymerase among acidophilic thermophiles is a logical step. Methanogens and strict halophiles are not necessarily known for their heat tolerance, and proteobacteria and cyanobacteria are diverse groups that may or may not have heat-tolerant DNA polymerases.
