Which statement about DNA replication is correct?

A correct statement about DNA replication is: “DNA replication results in two DNA molecules, each consisting of one original strand and one newly synthesized strand.” This describes the semi-conservative model of replication, where each of the two new DNA molecules retains one strand from the original molecule, ensuring genetic fidelity. This model was proven through experiments by Meselson and Stahl, providing evidence that DNA replication does not produce identical copies but rather preserves half of the original molecule.
