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 ...

How does grass grow in the extremely hot soils of Yellowstone National Park? Could a protein from a virus help plants handle global warming? Okay, that second sentence is wild speculation, but we will try to find the answer to our mystery by aligning our protein sequence to a sequence from a related structure.
