Common Sense for the Biochemist

So if you know anything about DNA, then you know that in it's native form, it exits as a helix with a right-handed twist. If you don't know anything about DNA, then it still exists in a helical form with a right-handed twist. In very rare circumstances, you will find DNA forming a left handed helix, but this is very uncommon. That is, unless you believe what the mass media tells you. The left-handed DNA hall of fame has cataloged those instances where the "artist" in charge of creating a pretty picture of a DNA helix has not consulted with his local molecular biologist for accuracy (or the local molecular biologist got his degree from the internet). Check it out.
