These re actually 2 questions, since I only have 10 points, Exam 1.03 Biology How do the hypothesis of microspheres and the RNA World hypothesis build off of each other? AMicrospheres were important for storing and releasing energy for surrounding organisms that contained RNA.
B Nonorganic molecules self-replicated within the early microspheres, similar to the way cells divide.
C Replicating RNA molecules transformed into DNA within the microspheres.
DWhen microspheres split, the genetic coding in self-replicating RNA would pass to the newly formed microspheres.
