Regulation of gene expression very commonly involves transcriptional regulation. The most important significance of this is that it:

1. is highly efficient at completely preventing transcription.
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.
