DNA Replication
Imagine you were to repeat Meselson and Stahl’s experiment. You would first grow E. coli bacteria in a medium containing 15N, which would make the DNA heavier than natural DNA, which contains 14N. You would then transfer your bacteria to a medium that contains 14N.
Required:
Question: If DNA replication were conservative, what weight(s) of DNA would you expect to see in your bacteria after one round of replication?
Please explain your answer.
