Final answer:
PCR typically results in the generation of fragments of all sizes.
Step-by-step explanation:
The statement is True. PCR (Polymerase Chain Reaction) is a laboratory technique used to amplify a specific DNA sequence. It involves repeated cycles of melting, annealing, and extension. During the extension step, DNA polymerase adds nucleotides to the growing DNA strand, resulting in the generation of fragments of all different sizes.
