Biology as a second-language: the immersion method Language teachers say the best way to learn a language is by total immersion and even better, spending time in the country where it’s spoken conversing with native speakers. See it, hear it, speak it, use it! Put yourself in a position where you must do these four…

Two protein structures from an avian influenza virus are shown below. One form of the protein makes influenza virus resistant to Oseltamivir (Tamiflu®) Don’t worry, these proteins aren’t from H5N1, but they do come from a related influenza virus that also infects birds. technorati tags: molecular models, protein structures, influenza, bioinformatics, Cn3D

Here’s a lovely DNA structure from our friend, human immunodeficiency virus I. I especially like the way that two heart-like shapes appear in the structure. tags: DNA structure, DNA , molecular structure, biochemistry

Last Friday, we had another in the series of weird DNA structures. (You can see the first here). I asked the audience to identify the unusual feature in this molecule. Here’s the first picture: tags: DNA structure, DNA , molecular structure, biochemistry Here’s the answer:

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,…

Although, I didn’t believe it when I first saw it. With all the years that I’ve heard (or taught) that all DNA is antiparallel, it was hard to believe my eyes. Yet here is parallel DNA, with both strands oriented in the same direction, right here on your monitor. And the commenters were correct. tags:…

A DNA puzzle

Okay, all of you biochemists and molecular biology types. I have a puzzle for you that I found by accident during a lecture. Yes, I was the one lecturing and the notes will be posted soon. In the meantime, here’s your puzzle: What’s unusual about this pair of bases? tags: DNA structure, DNA , molecular…

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. tags:…

tags: plants, bioinformatics, sequence analysis, viruses, fungi How does grass grow in the extremely hot soils of Yellowstone National Park? The quest continues. Read part I, part II, part III, and part IV to see how we got here. And read onward to see where will we go.

The wind storms and heavy rains that hit Seattle recently, demonstrated why a bypass mechanism can be a helpful thing – for both bacteria and motorists. Under the bridge on Mercer, from the Seattle Times
