If so how much different. Has pictures actually been taken of DNA? Any links or info?
No. DNA is a molecule and looks pretty much the same from single celled organism all the way through gigantic blue whales. Many pictures have been taken but it is too small to be viewed through conventional (i.e. visible light) methods, so those pictures will tend to be representations of what it looks like rather than what your eyes would see. If you're interested, just do a google image search for the terms "DNA" and "TEM" or "DNA" and "AFM".
As for the pattern of DNA, even that isn't too much different among various races. DNA has given scientists the ability to see that while some very specific patters can somewhat separate traditional races, the sociological idea of race doesn't have a particularly good scientific analog.
NO. Any fertile human male can do any fertile human female and make babies that can grow up to make babies too. That is the definition of a species... And we ARE a single species.

But are we a polytypic species? That is two or more subspecies.
Can you prove that?

I guess it depends on what certain terms entail. How clearly definitive are these lines between genera, species, subspecies, etc. I only ask the question - it seems like a good case could be made for subspecies.

So am I
I asked a question about whether there are subspecies within the human species and you responded with 'can you prove that' - I then said it really depends upon how we define those terms. I have no idea why you would respond with the above?

I consider "Neanderthals" a subspecies. Everyone one this earth is of the same species, just different ethnicities.
