Vedclass · Answer

(A) The Polymerase Chain Reaction $(PCR)$ cycle consists of three main steps:$1$. Denaturation: The double-stranded $DNA$ is heated to approximately $94^{\circ} C$ to separate the strands. This corresponds to label $B$.$2$. Annealing: Primers are added to the single-stranded $DNA$ at a lower temperature $(40-60^{\circ} C)$. This corresponds to label $C$.$3$. Extension: The enzyme Taq polymerase adds nucleotides to the primer,extending the $DNA$ strand at $72^{\circ} C$. This corresponds to label $A$.Therefore,$A$ is Taq polymerase,$B$ is Denaturation at $94^{\circ} C$,and $C$ is Primer.

Study the following diagram of the Polymerase Chain Reaction $(PCR)$ and identify $A, B$ and $C$.
