Give the name of the organism from where the thermostable DNA polymerase is isolated. State its role in genetic engineering.

Text Solution

Verified by Experts

Bacterium Thermus aquaticus is a source of enzyme Tag polymerase. As, it is a thermostable enzyme and works at high temperature, it is used to amplify DNA in vitro by PCR. The amplified fragment of desired DNA can be used to ligare with the vector for further cloning .
