Today's "molecule" isn't a molecule. I'm looking for the technique that's illustrated by the example shown here. Describe the technique and identify the Nobel Laureates who discovered it.
The first person to identify the technique and the Nobel Laureates, wins a free lunch. Previous winners are ineligible for six weeks from the time they first won the prize.
There are only two ineligible candidates for this week's reward: Alex Ling of the University of Toronto, and Markus-Frederik Bohn of the Lehrstuhl für Biotechnik in Erlangen, Germany.
I have an extra free lunch for a deserving undergraduate so I'm going to continue to award an additional prize to the first undergraduate student who can accept it. Please indicate in your email message whether you are an undergraduate and whether you can make it for lunch.
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule(s) and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Prizes so you might want to check the list of previous Sandwalk postings by clicking on the link in the theme box.
Correct responses will be posted tomorrow.
