"Genes encode proteins and do not contain any other information": this is entirely false. It's well established that genes contain non-encoding regulatory regions (which happen to be very important for the process we're discusion).

All the cellular machinery ultimately derives from genetic regulation and protein expression. You can't make more of it wihtout making more mRNA, translating that to protein.

This is bio 101, basic stuff, unless I'm completely misreading what you're saying.
