Question

In the PCR (Polymerase Chain Reaction), repeated temp cycles of what occur for each cycle?

Answer 1

The PCR cycle in each cycle involves denaturation, annealing, and DNA synthesis.

Step-by-step explanation:

The PCR (Polymerase Chain Reaction) cycle consists of three steps: denaturation, annealing, and DNA synthesis. Each cycle starts with denaturation, which involves heating the DNA to break the bonds holding together the two strands. Next, the temperature is lowered for annealing, where short DNA segments called primers attach to the single strands of DNA. Finally, the temperature is raised for DNA synthesis, allowing an enzyme called Taq polymerase to extend the primers and create new DNA strands.
