Question

This image depicts the three alternative models for DNA replication that were proposed before Meselson and Stahl devised experimental procedures to distinguish which happens in the cell.

Panel A depicts the Answer: semiconservative /dispersive /conservative model of DNA replication.

Panel B depicts the Answer: conservative /semiconservative /dispersive model of DNA replication.

Panel C depicts the Answer: conservative /dispersive /semiconservative model of DNA replication.

Panel C depicts the Answer: conservative /dispersive /semiconservative model of DNA replication.

Explanation / Answer

Panel A depicts: Semiconservative model of DNA replication because one parent strand retained and one newly synthesized daughter strand is present in each of the replicated double stranded DNA.

Panel B depicts: Conservative model of DNA replication either both parent strands or both newly synthesized daughter strands are present in the replicated double stranded DNA.

Panel C depicts: Dispersive model of DNA replication because segments of both parent strands and newly synthesized daughter strands are present interspersed in the replicated double stranded DNA.
