When Lipids, Phosphates, Carbohydrates and RNA Were Placed on Clay

Question 3

Multiple Choice

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.
