Final answer:
Yes, Taq polymerase is isolated from a thermophilic bacterium called Thermus aquaticus, which makes it very suitable for PCR due to its ability to withstand high temperatures.
Step-by-step explanation:
It is true that Taq polymerase is isolated from a thermophilic bacteria. Taq polymerase is a DNA polymerase that is particularly useful in PCR (polymerase chain reaction) because it can withstand high temperatures typically used in the PCR process. The Taq polymerase is synthesized by the thermophilic bacterium known as Thermus aquaticus, which thrives in the hot springs of places like Yellowstone National Park. This enzyme is thermally stable and can function effectively at temperatures that would denature most other enzymes. It maintains activity in a temperature range of 22°C to 89°C, with an optimum temperature of around 72°C, making it ideal for the denaturing and annealing steps of PCR.
