The text states that ribonucleotides can diffuse through some types of liposomes. It is likely that the lipids present early in chemical evolution had short chains. Would liposomes formed from these types of lipids be more or less permeable to ribonucleotides than if early cells formed from long-chained lipids?
A) more permeable
B) less permeable
C) same permeability

Short-chained lipids would have more fluid and disordered bilayers, which would be more permeable to small molecules like ribonucleotides. This means that liposomes formed from these types of lipids would be more permeable to ribonucleotides than if early cells formed from long-chained lipids.
