The central dogma doesn´t account for reverse transcription, wich is the recoding of the information contained in an RNA molecule, into a DNA molecule. This is accomplished by viral enzimes and enzimes coded by certain genetic mobile elements called retrotransposons (also of viral origin) which "read" RNA to make a DNA copy encoding the same information.
For these viruses, gene expression is not wholy explained by the central dogma. |

The two terms certainly are related. The central dogma is kind of a general principle about the flow of information in the cell. Gene expression refers to the process itself, and is therefore more comprehensive. For example, part of our knowledge about gene expression is that it is regulated based on the environment of the cell. This kind of feedback isn't really specified in the central dogma. Indeed there are "exceptions" to the central dogma. It doesn't account for the fact that much DNA codes for RNA only and that some of the "information" of the DNA is used only as a bonding site for regulatory elements. It also, of course, doesn't account for cases of reverse transcription. |

According to the Central Dogma of Molecular Biology, the DNA makes RNA which in turn makes Protein. The gene expression also refferse to the same process in which the ultimate result is formation of proteins from genes(or DNA).
The question is, how can these two terms be differentiated? |
