This is a fun puzzle. The pink molecule is a protein and the other molecule is a nucleic acid.

The grocery store magazine covers all say that home made gifts are big this year. So I thought, some of you might like to channel your inner Martha Stewart and make gifts with a science theme. I’m here to help to you make a merry mug with one of our favorite molecules. Yep, we’re talking…

Irony in RNA: a puzzle

This structure is called a “kissing loop” and I find that name just a bit odd, given the source of the structure.

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…
