I've had some requests for some more molecular puzzles since the last one that I posted (see A DNA puzzle ). One person liked it so much he even blogged about it.
So, here's one for you to chew on over the weekend.
This puzzle is a variation of an activity in Exploring DNA Structure, a CD/lab book that I made (with funding from the NSF) and used for some educational research.

Any ideas?

I'm going to hazard a guess and posit that it is A-DNA. B-DNA has a central axis of H-bonding and Z-DNA is left-handed, and has nucleotides spaced farther apart.
I am not, however, going to posit that my hazarded guess completely correct.
Is that an oxygen I see attached to the 2' carbons on the right hand strand?
Kind of looks to me like RNA hybridized to DNA.
Interesting guesses.
I'll post the answer on Friday.
