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

Conservative mode of replication

Explanation:

Meselson and Stahl performed the experiment to test how the DNA molecule replicates in the organisms.

He performed the experiment on E. coli by culturing them in N¹⁵ isotope and then transferring them to N¹⁴ isotope.

When he analysed the DNA sample through density centrifugation he found that in Generation One or one round of replication the intermediate band between the N¹⁴ isotope (lighter) and N¹⁵ isotope (heavier) isotopes.

This result showed that now the DNA contains both forms of isotope that is it is in favour of the semi-conservative and dispersive mode of replication but not conservative mode pf replication.

Thus, Conservative mode of replication is the correct answer.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
