Question 19 of 402.5/ 2.5 PointsSome 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 youhave recreated such a life form. What would demonstrate that RNA, but not protein or DNA, isnecessary and sufficient for these functions?A. The organism lives and replicates despite RNase and DNase treatment, but the organism
