Do proteins have free will? And other cartoons…

Finally a new batch. This time the themes are whether proteins have free will and a taste-test by ribosomes…

Feel free to use and repost – just give credit to the artist and provide a link to this website!

More cartoons appear in the monthly MDC newsletter Insights, so be sure to visit the website and check out some of our more “serious” content there!




And now for the ribosomes:



And once again, to kill the joke by explaining it:

Ribosomes build proteins by reading a three-letter code in RNA molecules (called a codon) and matching it to one of 20 amino acid building blocks. The nucleic acids “GAA” spell the code for glutamic acid, which is responsible for the taste of seaweed and is the source of monosodium glutamate.
