Trait : meaning of TRAIT in Hindi - Definition and Translation.
That left the scientists with only two options: either DNA replicated semiconservatively, as Watson and Crick had predicted, or it replicated dispersively. To differentiate between the two, Meselson and Stahl had to let the cells divide again and then sample the DNA after a second round of replication.
Convincing experimental evidence for a âsemiconservativeâ mode of DNA replication was first provided by the elegant experiments of Matt Meselson and Frank Stahl ( 1), in which differential labeling with nitrogen-15 (15 N) and nitrogen-14 (14 N) was used to resolve parental and daughter DNA molecules by equilibrium sedimentation in a CsCl density gradient.
