It is probably impossible to get cells (any cells) to reproduce at 10 times in a second. Very simple bacterial cells in optimum conditions for growth, for example, have a doubling time of ~ 20 min. Cellular reproduction requires a considerable amount of biological material to be synthesized (e.g. DNA, proteins, lipids, carbohydrates). The rates of the chemical reactions and the rates it takes these compounds to be transported throughout the cell would place a fundamental limit on the doubling time of an cell. For example, the rate at which DNA polymerase enzymes can synthesize DNA is somewhere in the range of 10-100 nucleotides per second, so it would be difficult for these enzymes to synthesize even a minimal genome in a fraction of a second. Even if these enzymes were made to be "perfect catalysts" (the reaction rate is limited only by the rate of diffusion of the reactants), I don't think they could support a reproduction rate as high as 10 times per second. My guess as to the upper limit would be on the order of the rates seen in bacteria: tens of minutes. Perhaps one day we could design simple cell-like systems with doubling times on the order of minutes.
It is possible, however, to engineer human cells in ways that they can't stop reproducing. This is, essentially, what cancer cells are: cell that have accumulated mutations that allow them to replicate uncontrollably and indefinitely. A good discussion of factors required for cells to become "immortalized" is given in the following review by Hanahan and Weinberg, "The Hallmarks of Cancer" (http://www.weizmann.ac.il/home/fedomany/Bioinfo05/lecture6_Hanahan.pdf [Broken]).
No i think it would kill you, because you would need cells to die at a equal rate, if not you would split your organs and bleed out. plus if your on about just some cells for people in post trauma they still need to get rid of the dead or damaged cells by braking down into there parts which takes time. so no i think it would kill you even if you needed more liver or what ever cells. Is that what you ment in your question. Plus as your dna copys as rna it loses a small amount of info cant remember the name of it but if i am wrong correct me
thank you for giving answer to my question . i thought that by changing , modifiing the dna we can be able to do every thing .
well i have another question . there are some types of small lizards that if you cut their tail they are able to produce another one, but without causing cancer. their tail cells reproduce in a special way or something , and can we change our dna so our cells reproduce that way ?
Em maybe someday not for 50 years at least. Because there is to much there bone skin ect but maybe in a lab and then with surgery put on. As for playing with dna we cant, not with such a very small part of it like that because if we do rna cant be picked up and taken somewhere in the body to be made into a new cell. But if you were fix it so a cell could be copyed an unlimited number of times you would get into other problems
Grow a arm for a person who has one taken of in a few months maybe. If so it will help. If it is made with your own dna it wont be rejected i think. forget arms think now of livers, kidneys, hearts, ect with current research it may happen cost and other things need to be taken into account time will tell. I think it is very cool and very exciting time in science now
yes of course that was what i was talking about. think of all disabled persons that have lost an arm or a leg or need a new heart or something ,they could get a new heart or arm and say goodbye to the poor disabled life just by paying a small price
