Statement-$I$ is correct but Statement-$II$ is incorrect.

Vedclass · Answer

(B) Statement-$I$ is correct because the thermostable $	ext{DNA}$ polymerase,known as $	ext{Taq}$ polymerase,is indeed isolated from the thermophilic bacterium $	ext{Thermus aquaticus}$.Statement-$II$ is incorrect because $	ext{Taq}$ polymerase is specifically used in the Polymerase Chain Reaction $(	ext{PCR})$ because it remains active and stable at high temperatures,including the extension step at $72^{\circ}	ext{C}$. It does not denature at these temperatures.

Statement-$I$: Thermostable $\text{DNA}$ polymerase is isolated from $\text{Thermus aquaticus}$.
Statement-$II$: $\text{Taq}$ $\text{DNA}$ polymerase is inactive at high temperature $(72^{\circ}\text{C})$.
