In the meselsons and stahls dna reproduction experiment, Ask an Expert

Academics

In the Meselson's and Stahl's DNA reproduction experiment, "parent" bacteria were grown in the medium of heavy nitrogen (15N) and then allowed to produce thereafter in light nitrogen (14N) media. Since replication is semi-conservative,

A) The next generation is hybrid or mid-weight (15N-14N), and the after generation is 25% heavy, 50% hybrid, and 25% light nitrogen.

B) The second and all subsequent generations will be the hybrid (15N-14N) strands.

C) The second generation will be hybrid (15N-14N) strands, and all later generations will regress towards higher proportions of light nitrogen (14N).

D) The next generation will be all light (14N) since heavy nitrogen will be corrected as the reproduction error.
