Question 4 0.5 pts Imagine that you are an astrobiologist charged with the task of figuring out how DNA replication works in a single celled organism found on a meteorite (yes, the alien organism had DNA!!!). You conduct an experiment where you allow the organisms to grow in a medium that has an altered form of nitrogen that glows green when it binds with carbon to form nitrogenous bases. So all the DNA in cells growing in this medium glow...
