text: do you ever think about the meaning of your life? if you do..then you'd better take a look at this question.. *dna-exists for one sole reason-to create more dna or replicate itself..in every of your cell you got 2 metres of this stuff if extended to the length.every dna bind or structure comprises 3.2 billion coding nucleotides  such as:thymine,adenine,guanine,cytocine,urasil with which it  is possible to form 10^ 3 480 000 000  probable biochemical and organical combinations..-,*guaranteed to be unique against all concievable odds.* as christian de duve notes..+"an obligatory manifestation of matter,bound to arise wherever conditions are appropriate,such conditions would be encountered perhaps million times in every galaxy.life seems inevitable in other words"...after these words  does the life has some concrete purpose to accomplish? slend of course it does, even the miracle of our dna proves it;  god created us in his image,for his glory, the bible tells us; just  think about that; & now this cloning thing, what next?? really, our bodies are pretty complicated, unique & it so amazing!!!!i don't know if this has anything to do with what you were looking for in  an answer, but it's what i beleive.
