Question 1
1) 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) same permeability
B) less permeable
C) more permeable
Correct Answer
C
Question 2
