Guest Fadi Posted April 26, 2003 Report Share Posted April 26, 2003 Here a head brackin question. After procreation, there is on cell deviding, this cell is a non-specialised cell, it devide a duplicate, all those cells are technically identical with the same core, the same membrane, and everything in between... after this cell multiplication and this dividing etc... every cells start being specialised, (brain cells, cardiac cells etc...), and so on the organism is created. If all those cells all came from this first procreation cell, and that they were all identical, how would each cells know in what it will get specialised ? I mean, they are all the same, so they got the same "programmation" they are therfore supposed to be transformed of the same type of cells... and how one cells would know what is the quantity of lets say brain cells, in order to say, O.K there is enough brain cells, bone cells are needed so it will specialise in that etc... Its funny how those cells start specialising in one field when they were all identical in the first place, and that the proportion was just good enough to permit the existance of the organism. Has anyone though of that ? Quote Link to comment Share on other sites More sharing options...
Sip Posted April 26, 2003 Report Share Posted April 26, 2003 It's all in the DNA from what I hear The entire map of the human body ... down to the last detail ... all encoded with Thymine, Adenine, Cytosine, and Guanine sequences!!!!! It's quite fascinating as you pointed out but the base map is all there. Now exactly which parts of the DNA get activated at what point in time and how, that's the question you're asking but I don't think that part is as exciting as the fact that the ENTIRE information is encoded there in EACH DNA instance in EACH CELL!!!!!!! WOW. Talk about compact representation and redundancy in data!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
Guest Fadi Posted April 26, 2003 Report Share Posted April 26, 2003 Yes of course it is in the DNA, the problem is that this same DNA duplicate from the RNA copying technic, but now after this duplication those two DNA are identical in nature, how one cell will become a neuron cell and the other a cardiac cell is behind understanding, since both are technically identical.
