When lipids, phosphates, carbohydrates and RNA were placed on clay, a lysosome was formed. Why was the clay an important surface for lysosome formation and how is RNA associated with the lysosome?
A. Clay acts as a catalyst for the formation of a lysosome that can grow and divide; the RNA would be enclosed inside of the lipid bilayer.
B. Clay would cause anions to stick together, while the cations would be pulled from the carbohydrates. This chemical reaction would cause the formation of a carbohydrate membrane. RNA would be part of this membrane.
C. The clay surface had nothing to do with the formation of a phospholipid bilayer; water would have worked just as well. RNA would be a transmembrane catalyst.
D. The positively charged clay surface would react with the negatively charged phospholipids to create a clay ball that would enclose the RNA molecule.
E. RNA would react chemically with the negatively charged clay surface. This would create covalent bonds; an impenetrable membrane would form. The phospholipids would be caught inside of the membrane.
