It takes quite a while until polymerization starts, but once it has, the process is autocatalytic until the physiological maximum of the polymerization rate is reached.

The Chairman of the Institute, Stuart Kauffman has contributed to the field of abiogenisis with his research into the emergence of metabolism through phenomena involving autocatalytic sets.
43.
Prior to Crick, biologists considered autocatalytic sets the way metabolism functions in principle, i . e . one protein helps to synthesize another protein and so on.
44.
Several models of the origin of life are based on the notion that life may have arisen through the development of an initial molecular autocatalytic set which evolved over time.
45.
It is therefore hypothesized that such systems may be able to evolve into autocatalytic sets of self-replicating, metabolically active entities that predate the life forms known today.
46.
In this clock the induction period is the time it takes for autocatalytic process to start after which the concentration of free iodine falls rapidly as observed by UV / VIS spectroscopy.
47.
In prokaryotes and eukaryotes, it is an enzyme that consists of two polypeptide chains, a heavy and a light subunit, processed from a single chain precursor by an autocatalytic cleavage.
48.
If one of these autocatalytic processes started to generate the class of fatty chemicals known as lipids, these might form a bubble around the system, and the first cell would be generated.
49.
Subtilisin, which is produced by " Bacillus subtilis ", is produced as preprosubtilisin, and is released only if the signal peptide is cleaved and autocatalytic proteolytic activation has occurred.
50.
According to the RNA world hypothesis, RNA sequences performing both enzymatic and information storage roles in autocatalytic sets were an early unit of selection and evolution that would later transition into living cells.
