Solution
The correct option is C Thermus aquaticus
- The thermal cycler is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction (PCR).
- It is also known as a thermocycler, PCR machine or DNA amplifier.
- Thermal cyclers may also be used in laboratories to facilitate other temperature-sensitive reactions, including but not limited to restriction enzyme digestion or rapid diagnostics.
- Later, the PCR process was adapted to the use of thermostable DNA polymerase enzyme from Thermus aquaticus, which greatly simplified the design of the thermal cycler.
- So, the correct answer is 'Thermus aquaticus'
