The semi-conservative nature of replication was established by Meselson and Stahl in their classic experiment with bacteria. They grew bacteria in . containing medium, washed and then incubated in fresh medium with - containing compounds and allowed to grow for three generations. density gradient centrifugation of isolated established the nature of semiconservative replication. The pictorial representation below shows the position of differentially labeled in density gradient.
Had the replication been conservative, what would have been the pattern?
