If so, can RNA control the growth and division of the membrane?
Section 3.4 - 'There is a debate whether CMIO could have formed by a CCSI consisting entirely or mainly of RNA'. This section seems to mix up two important questions. (i) Are RNA catalysts sufficient? Do we need other kinds of biomolecules like protein catalysts? (ii) Do we need the RNA system to be enclosed in a cell membrane or other kind of compartment? If so, can RNA control the growth and division of the membrane? These issues need to be considered separately.
