Description
This is the best Genetic Code chart ever! For novices, that is.
Those 20 proteinogenic amino acids are real characters! Each has its own charming personality. They do fall into four nice categories of side-chain chemical quality, indicated by colored backgrounds.
The idea for drawing side-chain atoms as kissing circles, and the representation of the invariant amino acid backbone as a simple chain-link, came from Mahlon Hoagland and/or Bert Dodson. Page 121 of their wonderful 1995 book The Way Life Works (out of print but still available secondhand in many bookstores) has the chart which formed the basis for this one. I just fixed a few problems with the original. Relative atomic radii are now correctly depicted, and elements have the conventional color-coding, and all the atoms are now in the right places. The background color code is new too.
This is the DNA version of the Code. The RNA version, with U instead of T, will also be available for free.
The PDF resolution is sufficient for large-format (poster) printing. 8.5x11 is also fine. You're welcome!
