I can't beleive it's been trademarked.
- What an asshole.
  
  At least it's trademarked by a guy that wants to protect it and not a corporation that would sue anyone who uses it.
  
  I definitely don't think it should be able to be trademarked at all though.
  
  Did you even read the article? He did it for preservation purposes.
My dad saw this painted on a sidewalk recently and was really curious what it meant. He was disappointed I think to hear it was just a “cool S” so maybe I’ll send him this comic!
If only Rosalind had found it out this way, instead of all that radiation giving her cancer
So that means teenage-me helped discover DNA? Heck yea 🤘
Doodled by someone in their brain on lsd is what I heard. The l double helix I think it was.

But yes all children draw this S everywhere in the world for no reason.
- am draw ._. instead

  Kilroy was here
The double helix depicted in the comic twists the wrong way (inverted chirality).

Randall, I'm disappointed in you :)
No no, I said consummate S!
DNA is a double helix. The image bottom right shows only a single helix. For a double helix, think of a rollercoaster riding the track. There needs to be 2 rails going around for the rollercoaster to attach to.
- It's a double helix.
  
  But it's not. Most people think DNA and the double helix look this this
  
  But that a common misconception. A true double helix (and DNA) look like this
  
  I know this cause I have a DNA tattoo looking like the first one and have been corrected once or twice haha
  
  Yeah, ok I see it now. I was looking at it as a thick bar on the outside where that could be better viewed as a double line.
