If E. Coli grown in 15N medium is transfered to 14N medium and allowed to grown for two more generations...? - e.coli more condition_treatment
DNA and centrifuged. What is the distribution density of the DNA can be expected in this experiment?

E.coli More Condition_treatment If E. Coli Grown In 15N Medium Is Transfered To 14N Medium And Allowed To Grown For Two More Generations...?

Semi-conservative DNA replication.
The 15N with E. coli E. coli is heavier than 14N) (father.
The first generation of E. coli is both 15N and 14N. Thus, the density in the competition in the middle and 14N to 15N. (E. coli 15N-14 N)
Thus, for the second generation of the DNA is replicated again. The second generation is similar to that of their parents. So with 2 Density 14N E. coli is easier and 15N E. coli is difficult.
Hope this helps.
