Yes, DNA replication is semiconservative. This means that when DNA replicates, each of the two resulting DNA molecules consists of one original strand (parental) and one newly synthesized strand. This method of replication was confirmed through the Meselson-Stahl experiment, which showed that the original DNA is conserved in each new DNA molecule, making the process semiconservative rather than conservative (where the entire original strand would be preserved) or dispersive (where segments of the original and new DNA would be mixed).
