I saw a similar question on your web site relating the lenght of human dna 
to other animals.  The answer I saw said 5cm.  I have to believe that is 
the length in it's original shape.  I also found an answer that stated a 
fruit fly's dna, if it could be straightened, would be twelve times its 
body lenght.  That is what I thought the answer should look like for a 
human as well. Still one more site stated that human dna seperated and 
tied end to end would be over five feet long. Please help me out. Thank 
You!
