Many years ago, some researchers reported that they could transfer learning from one animal (a flatworm) to another by feeding trained animals to untrained animals. Further, they claimed that RNA was the active molecule of learning. Given your knowledge of the roles of RNA and protein in cells, do you think that a specific memory (for example, remembering the base sequences of codons of the genetic code) could be encoded by a specific molecule of RNA and that this RNA molecule could transfer that memory to another person? In other words, in the future, could you learn biology by popping an RNA pill? If so, how would this work? If not, can you propose a reasonable hypothesis for the results with

- Not part of a graded assignment, from a past midtermarrow_forwardNoggin mutation: The mouse, one of the phenotypic consequences of Noggin mutationis mispatterning of the spinal cord, in the posterior region of the mouse embryo, suchthat in the hindlimb region the more ventral fates are lost, and the dorsal Pax3 domain isexpanded. (this experiment is not in the lectures).a. Hypothesis for why: What would be your hypothesis for why the ventral fatesare lost and dorsal fates expanded?
