The diagram should remind you of the cell cycle and the 2001 Nobel Prize in Physiology and Medicine. Since I already covered Tim Hunt and Paul Nurse, this must be about Lee Hartwell. That means the molecule must be "start" or CDC28.
The winner is Bill Chaney of the University of Nebraska. He has agreed to donate his free lunch to an undergraduate. Unfortunately, there weren't any undergraduate who got the right answer this week so I still have three free lunches to give away.
Sometimes it's almost impossible to find an image of a specific molecule that honors a Nobel Laureate. This is one of those times.
The diagram provides all the clues necessary to identify an important process and then to identify a particular molecule associated with this week's Nobel Laureate.
You must name the molecule and the Nobel Laureate. Be careful 'cause it's easy to make a mistake and name someone who has already been the subject of a Monday's Molecule.
The first person to identify the molecule and name the Nobel Laureate(s) wins a free lunch. Previous winners are ineligible for six weeks from the time they first won the prize.
There are only six ineligible candidates for this week's reward: Frank Schmidt of the University of Missouri, Joshua Johnson of Victoria University in Australia, Markus-Frederik Bohn of the Lehrstuhl für Biotechnik in Erlangen, Germany, Jason Oakley a biochemistry student at the University of Toronto, Dima Klenchin of the University of Wisconsin, Madison and Alex Ling of the University of Toronto.
Joshua and Dima have agreed to donate their free lunch to an undergraduate. Consequently, I have two extra free lunches for deserving undergraduates so I'm going 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. If you can't make it for lunch then please consider donating it to someone who can in the next round.
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.
