If you are suspended they would be able to get a perfect copy of all your DNA even if your body suffered massive genetic damage, since each cell has a complete copy and they would have many trillions to work with. One more cell would not be important. >> Information I've picked up on Cryonet and in casual reading of other publications has led me the following understanding... As you age, your DNA slowly mutates so that an old person's DNA in each cell may not be identical to the DNA of each cell at birth. I don't know if the mutations occur in all sets of DNA and I don't recall what the speculated cause of the mutations is. I do recall reading speculations that the mutations are numerous enough to be suspected as a general contributor to declining health in older people, the mutated DNA not expressing its cellular directions correctly, leading to malfunctioning cells throughout the body. So thats the idea behind storing DNA when you are young. To relieve the burden of future scientists of figuring out what your unmutated DNA looks like.
