A DNA molecule can be as short as one nucleotide base pair or as long as
billions of base pairs. If you take all the DNA in one human cell,
unravel it, join it end to end, and stretch it out, then the molecule
would be about six feet in length. You can see an animation of this at
our web site: DNA Interactive.
