You learn that a Mars lander has retrieved a bacterial sample from the polar ice caps.

You learn that a Mars lander has retrieved a bacterial sample from the polar ice caps. You obtain a sample of this bacteria and perform the same kind of experiment that Meselson and Stahl did to determine how the Mars bacteria replicates its DNA. Based on the following equilibrium centrifugation results, what type of replication would you propose is used by this new bacteria? Explain your answer.
