Uncoiled I believe it would be up to 5cm in length.

In human cells, the DNA is divided into 46 molecules (46 chromosomes), each of which would be about 1.5 inches long if stretched out.
46x1.5=69 About 69 inches if my logic is straight. (Don't have time to check)

Yes, maybe that's right Kayl - around 2 metres. Not sure what I was thinking of.

Good try Stew, but Kay gets the yay! That's 6 feet of DNA in every cell nucleus in the body. Isn't our biology impressively compact?

hey! that question is copyrighted :P
(ok fine it was a variant so I can't punish you to the fullest extent of the law since the law doesn't apply)

Sorry Wolfie. I did try a search on "genome" before I asked it.
