I really don't think that freeze thawing at -70 C will have any effect on your
DNA. Unless A  VERY HIGHLY ACTIVE DNase was mistakenly added to the sample
DNA.Besides why don't you save your DNA at 4C. I do it all the time and make
sure that Vial of DNase is on the opposite end of the fridge. :)
Good Luck.
