Orgel's First Rule
"Whenever a spontaneous process is too slow or too inefficient a protein will evolve to speed it up or make it more efficient."
This "rule" comments on the fact that there is a great number of proteins in all organisms which fulfil a number of different functions through modifying chemical or physical processes. An example would be an enzyme that catalyses a chemical reaction that would take place too slow to benefit an organism without being sped up by this enzyme.

Famous quotes containing the word rule:
“Freedom of men under government is to have a standing rule to live by, common to every one of that society, and made by the legislative power vested in it; a liberty to follow my own will in all things, when the rule prescribes not, and not to be subject to the inconstant, unknown, arbitrary will of another man.”
—John Locke (1632–1704)
