Continuation of Meselson and Stahl Experiment in E. coli
Meselson and Stahl's experiment demonstrated the semi-conservative replication of DNA. If this experiment is continued for four generations in E. coli, the ratio of N15:N15/N14:N14/N14 containing DNA's would be as follows:
First Generation:
- In the first generation, after one round of replication, the DNA would consist of equal parts of N15/N14 and N14/N14 DNA. The ratio would be 1:1 for N15/N14 and 2:2 for N14/N14 DNA.
Second Generation:
- In the second generation, after another round of replication, the DNA would consist of varying proportions of N15/N14 and N14/N14 DNA. The ratio would be 1:3 for N15/N14 and 2:2:2 for N14/N14 DNA.
Third Generation:
- In the third generation, the DNA would continue to replicate, leading to a further shift in the ratio of N15/N14 and N14/N14 DNA. The ratio would be 1:7 for N15/N14 and 2:2:2:2:2 for N14/N14 DNA.
Fourth Generation:
- By the fourth generation, the DNA would reach a stable ratio. The ratio would be 1:15 for N15/N14 and 2:2:2:2:2:2:2:2:2:2 for N14/N14 DNA.
Continuing the Meselson and Stahl experiment for four generations in E. coli would demonstrate the progression of DNA replication and the eventual stabilization of the ratio of N15/N14 and N14/N14 DNA.
