The essential requirements to maintain a living unit like the first cell are: organic energy sources; an information storage system; an expression system that uses the information to both exploit energy sources and to reproduce; and a method of containment to distinguish the living cell from the outside world. For each of the last three categories, identify the key molecules or groups of molecules used by the first cells that allowed them to maintain and propagate, and describe the properties/characteristics...
