Origin of life part 2 DNA

           DNA, the hereditary material in all living cells that carries the information to duplicate itself.Every human being has their own unique DNA code. The code is made up of four chemical bases:
            G- guanine
            A-aenine
            T-thymine
            C-cytosine.

             The order of the basis determines the information available for building and maitaining an organism. For example: The 24 letters of the alphabet can be rearrange to write everything ever written in English.
            Basically what we are examining is information, the blueprint to make another similar organism. But it doesn't do that by itself. It is necessary for enzymes to exist, various types of proteins that drive the chemical reaction required for a particular action.
             So the enzyme is the worker, taking it's orders from the information on the DNA and performs perfectly what is required of it.
              Now, we have the info and the enzymes that read the info and do what it says. A question that I have and could not find an answer to was: How could the information and the workers evolve seperately from DNA but need each other to replicate life? How does it know to do that?
              A piece of DNA that dictates a particular trait is called a gene.The amount of info in DNA is staggering, a DNA strand is only 10 atoms wide but if you stretched out the strands in your body it would be about 500 million miles long.This is all the information to build your bones,eyes,heart and every other part and function of your body.
             One of the mysterious of science is how  identical cells,with the same DNA, will divide to form your heart while others form the other body parts.
              One theory is that there are switches that turn some genes on while turning some off. Where are these swithches? Until scientist find them, I will submit this as evidence of design.
             You were conceived when an egg from your mother and a sperm cell from your father met to give you 23 chromozones from your mother and the same from your father. This have you your own genetic code. There has never been ,in all history, anyone like you.
              If a problem occurs in the process, the new cells, if they survive ,can cause problems.These are called mutations. Here is a real smoking gun as far as I am concrned: Some mutations are beneficial. This is the basis of all evolution theory, a beneficial mutation that allows an organism to develope capabilities it's ancestor did not posses.
              A mutation is a mistake, a G where it should have been a T. So how can a mistake in the blueprint lead to a benifit in the organism?Can a bunch of mistakesin DNA from the first One cell organism ,all the way to us ,be just mindless luck.
              So, maybe all mutations are not mistakes but an improvement in the design.
