Which of the following is a direct outcome of PCR?

The amplification of specific DNA sequences is a fundamental outcome of the Polymerase Chain Reaction (PCR). During this process, specific DNA fragments are targeted and exponentially replicated, resulting in millions of copies of the desired sequence from a small initial sample. This is achieved through a series of temperature cycles that include denaturation (separating the DNA strands), annealing (binding of primers to the specific target regions), and extension (synthesizing new DNA strands using a DNA polymerase enzyme). PCR is widely used in various applications, including genetic research, medical diagnostics, and forensic science, due to its efficiency and specificity in amplifying DNA sequences.
