The red arrow points to a lysosome and the blue arrows identify peroxisomes. The man who discovered and characterized these organelles is Christian de Duve (1974)
This week's winners are regulars: Dima Klenchin of the University of Wisconsin and undergraduate Alex Ling of the University of Toronto.
This Monday's "molecule" looks a lot like an electron micrograph of a cell instead of a molecule. That's because it's hard to connect a specific molecule with some Nobel Laureates. Your task today is to identify the two things identified by the red and blue arrows.
There's one Nobel Laureate who is closely identified with the discovery of these two things. Name this Nobel Laurete.
The first person to identify the images and the Nobel Laureate wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first won the prize.
There are eight ineligible candidates for this week's reward: Bill Chaney of the University of Nebraska, Maria Altshuler of the University of Toronto, Ramon, address unknown, Jason Oakley of the University of Toronto, John Bothwell from the Marine Biological Association of the UK, in Plymouth (UK), Wesley Butt of the University of Toronto, David Schuller of Cornell University, and Nova Syed of the University of Toronto.
Bill, John, and David have offered to donate their free lunch to a deserving undergraduate so the next two undergraduates to win and collect a free lunch can also invite a friend. Since undergraduates from the Toronto region are doing better in this contest, I'm going to continue to award an additional free lunch to the first undergraduate student who can accept a free lunch. Please indicate in your email message whether you are an undergraduate and whether you came make it for your free lunch (with a friend).
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Laureate(s) 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. I reserve the right to select multiple winners if several people get it right.
