2.	allows the cell to only produce proteins that are needed at the time.
3.	can be induced by a repressor protein.
4.	can be done only in prokaryotes.

It is believed that all organisms have arisen from a single distant ancestor. The strongest evidence for this would be:

1.	DNA stores genetic information in all organisms.
2.	The genetic code is universally a triplet code.
3.	The amino acids specified by particular triplets are almost always identical between any two organisms.
4.	The genetic code is degenerate but unambiguous.
