Editing Vesicle (biology and chemistry) (section)

===Protocells===
The [[RNA world]] hypothesis assumes that the first [[self-replication|self-replicating]] [[genome]]s were strands of RNA.  This hypothesis contains the idea that RNA strands formed [[ribozymes]] (folded RNA molecules) capable of catalyzing RNA replication.  These primordial biological catalysis were considered to be contained within vesicles ([[protocell]]s) with membranes composed of [[fatty acid]]s and related [[amphiphile]]s.<ref name="Adamala2013">{{cite journal |vauthors=Adamala K, Szostak JW |title=Nonenzymatic template-directed RNA synthesis inside model protocells |journal=Science |volume=342 |issue=6162 |pages=1098–1100 |date=November 2013 |pmid=24288333 |pmc=4104020 |doi=10.1126/science.1241888 |bibcode=2013Sci...342.1098A }}</ref>  Template-directed RNA synthesis by the copying of RNA templates inside fatty acid vesicles has been demonstrated by Adamata and Szostak.<ref name = Adamala2013/>
