Default Redundent DNA?

So much DNA is regarded as redundent - yet have we solved everthing? Yes we know that this part of the 'chain' causes this, and we certainly know that in for instance a muscle cell which part of the DNA is active. But I see very little mention of 'construction DNA' - whats that? Well I suggest DNA is doing two quite distinct but inter related operations: It is running each cell and in aggregate the body as a whole, but it has to construct the body and workings of the mind in the first place. Consider there is no over all master controller ( God excluded! ) All that is happening is that cells are dividing how do they 'know' which is to be arm which leg?
To illustrate what I am getting at I introduce Three theoretical properties of a cell: Identity, Orientation and Multiplication Factor (3D) and a totally ficticious description of the human growth process. Consider initially that the human body is in a 4 segment form, vestigial tail, pelvis with legs,thorax with arms,head and neck. In simple form the first division of the fertilized egg creates 2 cells and the construct DNA is so modified that one cell 'identifies' with being part of the upper body the other the lower, looking at the lower the next division has 'identifiers' for pelvic segment and tail if the tail finds itself next to the head then 'Orientation' causes both to die and the process repeated until the correct result is obtained. For the pelvic segment further division pruduces a left and right side ( symmetry ). The next stage limb vrs body, now for the limb a certain amount of controlled ( numbered ) mult and so on before splitting into upper and lower. Note for symmetry there must be some kind of count.
