Question

DNA polymerase enzyme is isolated from which bacteria?

• A. E.Coli
• B. Thermus aquaticus
• C. Bacillus thrunegenesis
• D. Agrobacterium

Answer 1

The correct option is B Thermus aquaticus

For the PCR technique, DNA polymerase enzyme is isolated from the thermophylic bacteria Thermus aquaticus. Hence, it is called as Taq DNA polymerase. It is a specialized thermostable enzyme. The enzyme is produced and expressed in the E. coli bacteria. It is used in polymerase chain reaction (PCR) technique where high temperature is required for copying DNA.

Thus, the correct answer is option B.
