In the meselson-stahl experiment, which mode of replication was eliminated based on data derived after one generation of replication?

a. conservative
b. semiconservative
c. dispersive
d. none of the modes

conservative model

Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.

CONSERVATIVE

Explanation:MESELSON-STAHL EXPERIMENT is an experiment carried out by Matthew Meselson and Franklin Stahl in the year 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative.

After the completion of the first replication cycle,it was discovered that the replication is not a complete conservative process but a semi-conservative in nature. It shows that when DNA replicates one of the Helical strand is from the

one strand from the original or old helix and one newly synthesized helix.

answer; i believe the correct answer is (anemia);
