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.
Transcript: The structure of DNA, that Watson and Crick discovered, suggests how genetic information is passed on. Before a cell divides, the double helix unwinds and the two strands of the DNA molecule in the nucleus separate.Each strand is then used as a template for the construction of new DNA molecules. The replication of DNA is simple in theory, but much more complicated in reality.ranscript: The structure of DNA, that Watson and Crick discovered, suggests how genetic information is passed on.
