Monday's Molecule #94

 
Most of you should recognize this molecule. You must describe both parts of the molecule, making sure to state clearly what you are seeing. As an extra challenge, you have to specifically mention something that is not shown even though it might be normally considered part of the complex.

It's a short step from there to this week's Nobel Laureate(s) but you need to be careful. There are two possible answers and one of them has already been chosen. You have to pick the other one.

The first one to correctly identify the molecule and name the Nobel Laureate(s), wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first collected the prize. There are three ineligible candidates for this week's reward: Alex Ling of the University of Toronto, Haruhiko Ishii, and Bill Chaney of the University of Nebraska.

THEME:

Nobel Laureates
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.

Comments will be blocked for 24 hours. Comments are now open.

UPDATE: Several people recognized that the molecule is a nucleosome. The figure on the left show the conformation of the histone core consisting of histones H2A, H2B, H3 and H4. The figure on the right shows the same protein core (rotated) with DNA wrapped around it to form the nucleosome core particle. The fifth histone, H1, is part of the linker region and it isn't shown.

Nobody guessed the Noel Laureate. It is Albrecht Kossel. There is no winner this week.
