Monday's Molecule #222

Last week's molecule was D-serine. (Not L-serine.) The winner is undergraduate Zhimeng Yu [Monday's Molecule #221].

I was reminded of this week's molecule by a discussion we are having in an evolution forum and by a comment from a student who took a MOOC on genetics. Does it depict something that should be taught in every introductory genetics course? Is it something that should be discussed in an evolution course? You need to name the structure formed by the blue, gray, and black strands. It has a specific name.

Email your answer to me at: Monday's Molecule #222. I'll hold off posting your answers for at least 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!)

In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.

Winners will have to contact me by email to arrange a lunch date. Please try and beat the regular winners. Most of them live far away and I'll never get to take them to lunch. This makes me sad.

Comments are now open.

UPDATE: It's a Holliday junction, one of the key intermediates in recombination. It's named after Robin Holliday who has since retired from science to concentrate on being a sculptor. He has produced several "biological" sculptures including "DNA Structure" (top) and "Cross Over" (bottom). The winner is Caroline Josefsson from British Columbia. The undergraduate winner is Andrew Wallace but since he lives in Australia, I suspect he won't be coming to lunch.
