Answered

DNA replication is called semiconservative because, during the process, each of the two resulting DNA molecules contains one strand from the original DNA (parental strand) and one newly synthesized strand. This ensures that one-half of the original DNA is conserved in each of the two new DNA molecules. This method of replication was first demonstrated in the 1950s by the Meselson-Stahl experiment, which showed that after replication, the DNA molecules were a hybrid of old and new strands.
