In the process of creating proteins, the DNA of course requires the use of raw materials from outside the nucleus located in the cell itself. These raw materials of course got there because when the cell was formed as a certain kind of cell its purpose was to get just those raw materials. That is why different cells have different functions and produce different proteins even though theoretically they could produce any protein at all since they all have the same DNA code.
What all this leads to however is a sort of chicken and egg problem - which came first the DNA or the cell? This is a really big problem for those who believe abiogenesis is possible.
One regulator controls many downstream genes, just as one foreman gives orders to several workers. These considerations hold regardless of whether we are talking about traditional protein-mediated control, or these novel siRNA-mediated mechanisms. Protein versus RNA is just a question of instrumentality, like JAVA versus C++.
Interesting that you mention programming languages in the discussion of gene regulation. You sound like an anti-evolutionist insisting that the genome is a program and was thus intelligently designed. Surely you do not wish to assert that programs are written and modified at random do you?
