Gene regulation and expression needs proteins in order to regulate the expression of genes.

Here's some questions.
How did the mechanics of the lac operon evolve?
Why does the repressor attach itself to the operator and how did the mechanics evolve?
Why does the repressor attach to the operator when lactose isn't present and how did the mechanics evolve?
Why do you have promoter, operator then genes and how did this sequence evolve?
What stops the RNA Polymerase when the repressor is attached to the operator? Why can't it express the lac genes and how did this mechanism evolve?
How did Repressors, Enhancers and Activators evolve and how did the mechanics evolve for there role in gene regulation?
Which evolved first the enhancers, activators, promoter region or DNA coding sequence and how did the mechanics evolve?
How did the bending protein evolve and how did the mechanics evolve where the bending protein folds the DNA strand to the spot near the promoter which activates gene expression?
Why does the activators attach themselves to the enhancers and how did the mechanics evolve?
Which evolved first gene regulation or gene expression? How did these things evolve and how did the mechanics evolve?
Gene regulation and expression needs proteins in order to regulate the expression of genes. Which evolved first, how did it evolve and how did the mechanics evolve? Did the expression come before the regulation or did they both just magically appear as a system that works beautifully together?
Adaptation to novel environments is often associated with changes in gene regulation. Nevertheless, few studies have been able both to identify the genetic basis of changes in regulation and to demonstrate why these changes are beneficial.
To this end, we have focused on understanding both how and why the lactose utilization network has evolved in replicate populations of Escherichia coli.
Here we focus on the regulation of a group of well-studied genes, the lac operon, that control the utilization of lactose

If we were designed by a creator I'd still like to know who designed the creator. If it's not possible for amazingly complex things to naturally evolve over time then we must conclude that something else created the creator. Saying that complex things must always be designed and can't arise naturally is a paradox... because then you are forced to say the creator couldn't have possibly arisen naturally. At the end of the day, the ONLY possible conclusion that one may reach is that given enough time even the most absurdly unlikely events will occur. It doesn't matter how unlikely those events are, they will eventually occur. And when extremely rare things like sentient life pops up they think "man there's no way we got here naturally".edit on 23/2/2013 by ChaoticOrder because: (no reason given)
The mechanics of a system based on code has to be put in place by intelligence. It's simply ignorant to me that people will even suggest that the mechanics of a system evolved naturally.

OP, why do you think non-coding DNA is blind to natural selection?
You do realise, I hope, that your argument stands or falls on your ability to answer that question...
Whenever we find out the causes of anything, it turns out to have been caused by some real thing and not a ghost, a god, or magic pixie dust.
Wth? "i don't know, so it must be an intelligent creator" please evolve your mind.

No it doesn't. Your question can be easily answered. It's just you trying to add weight to your question that isn't there. It's a high school question but I will answer it when you make an attempt to answer my questions.

All arguments against evolution are nothing of the sort.

Oh, those questions.
Do you expect answers to detailed problems in molecular biology from non-experts on a popular web forum?
Presumably you chose them because you know biology currently has no answer to them.
