For E to be true, then at least two of A, B, C, or D must be true.





A is false. There are cases where RNA makes DNA makes RNA and then protein. There are cases where DNA makes RNA and the end product is RNA.





B is true. There are always exceptions in biology.





C. is false because of A. There are exceptions to the central dogma.





D. I hope you understand why D is false.
