_______ is the source of the thermally stable DNA polymerase that was critical for the development of the widely used polymerase chain reaction (PCR) and can occur in domestic water heaters.
A) The hyperthermic bacterium Aquifex, which lives near volcanic vents,
B) The high-GC Gram-positive bacteria Mycobacterium tuberculosis
C) The hadobacterium Thermus aquaticus
D) The proteobacterium Escherichia coli
E) The thermophilic, acidophilic crenarchaeote Sulfolobus

Question

Quizplus · Accepted Answer

Thermus aquaticus is a type of bacteria that lives in hot springs and geysers, making it thermophilic. It is the source of the thermally stable DNA polymerase that was critical for the development of PCR, as it can withstand the high temperatures used in the reaction. This polymerase is commonly known as Taq polymerase.
