After Watson and Crick proposed the double helix structure for DNA, three models for DNA replication were proposed: conservative, semiconservative, and dispersive.;In the conservative model, the first replication produces one daughter molecule containing both parental strands and another containing all new strands.;In the semiconservative model, each parental strand is a template for a new strand. Each daughter molecule has a parental strand and a new strand.;In the dispersive model, each parental strand is broken into double-stranded segments that act as templates for new molecules. The segments then reassemble into complete double helices, each with parental and new segments interspersed.;Suppose you were a scientist evaluating these three models when they were first proposed. What would have been your hypothesis regarding which model was correct? Explain;Which two models have similar results after replication cycle 1?;Why were culture samples taken after each replication cycle?;Which model(s), if any, is ruled out by the experimental results of replication cycle 1? Explain.;Which model is proved correct by the experimental results of replication cycle 2? Explain.
