Taq polymerase

Vedclass · Answer

(C) The polymerase chain reaction $(PCR)$ is a technique used to amplify a specific segment of $DNA$.This process requires a heat-stable $DNA$ polymerase enzyme that can withstand the high temperatures used during the denaturation step of the reaction.$Taq$ polymerase is isolated from the thermophilic bacterium $Thermus$ $aquaticus$.It remains active at high temperatures and is essential for the extension step of $PCR$.

Column-$I$	Column-$II$
$(a)$ Ligase	$(i)$ It removes nucleotides from $DNA$ ends.
$(b)$ Endonuclease	$(ii)$ Connects parts of $DNA$.
$(c)$ Exonuclease	$(iii)$ Removes phosphates from $DNA$.
$(d)$ $DNA$ Polymerase	$(iv)$ It produces sticky ends in $DNA$.
	$(v)$ Useful for repeated amplification.

The enzyme required for the polymerase chain reaction $(PCR)$ is:
