A diagram illustrates the three-step polymerase chain reaction (PCR) process: Step 1 shows DNA denaturing at 95 degreesC into two strands; Step 2 depicts primers binding to target sequences during annealing at 55 degreesC; Step 3 shows DNA polymerase (Taq) synthesizing new DNA at 72 degreesC, resulting in DNA amplification, with the cycle repeated multiple times.
