Which statements are true? explain why or why not.
-You have begun to characterize a sample obtained from the depths of the oceans on Europa, one of Jupi- ter's moons. Much to your surprise, the sample contains a life-form that grows well in a rich broth. Your prelimi- nary analysis shows that it is cellular and contains DNA, RNA, and protein. When you show your results to a col- league, she suggests that your sample was contaminated with an organism from Earth. What approaches might you try to distinguish between contamination and a novel cellular life-form based on DNA, RNA, and protein?
