Some scientists have proposed that the earliest forms of life may have existed in an “RNA World” where RNA was both the genetic material and responsible for enzymatic activity. Imagine that you have recreated such a life form. What would demonstrate that RNA, but not protein or DNA, is necessary and sufficient for these functions?Feedback: Hint: Consider what you have learned about the experiments by Avery, MacLeod, andMcCartyQuestion 8 of 101.0/ 1.0 PointsChargaff’s rule is supported by what statement?Feedback: Learning Objective: State and explain Chargaff’s rules Learning Objective Text: Stateand explain Chargaff’s rules
