Biology
You are studying an alien bacteria-like organism isolated from the clouds of Venus. You decide to repeat the Meselson-Stahl experiment to find out how it replicates its DNA. This time you plan to grow the cells on light 14N medium for many generations first. Then, you plan to transfer them to heavy 15N medium and allow them to grow for 2 additional generations (2 rounds of DNA replication). If the alien replicates its DNA via the conservative model of DNA replication, what is the expected distribution of DNA in the density gradient after two rounds of replication
