Which model of DNA replication is currently accepted, stating that each new DNA molecule consists of one old strand and one newly synthesized strand?

  • A: Conservative
  • B: Semiconservative
  • C: Dispersive
  • D: Progressive

Explanation

The semiconservative model of DNA replication, proposed by Watson and Crick and later confirmed by the Meselson-Stahl experiment, states that each of the two new DNA molecules will have one old strand from the parent molecule and one newly synthesized strand. This ensures that genetic information is accurately passed on to daughter cells.
