Proteins that control genes

An interesting breakthrough in how the human genome actually works: many proteins are in fact controlling what genes do.

Of course, these proteins are ultimately a encoded by some genes, so the DNA code would still be the ultimate arbiter, but now it seems that the key may not be in the gene alone but also in those proteins that control its behavior, which in turn are generated by other "master genes".

This complex interaction beyond the simple "DNA rules" axiom may explain how humans, allegedly much more complex that other organisms like plants, have not more genes than them.
