How to use Cn3D

Have you ever wondered how to view and annotate molecular structures? At least digital versions? It’s surprisingly easy and lots of fun. Here’s a movie I made that demonstrates how you can use Cn3D, a free structure-viewing program from the NCBI. Luckily, Cn3D behaves almost the same way on both Windows and Mac OS X.…

If you look below the fold, you can see two molecules locked in a tight embrace. These molecules or their closely related cousins can be found in any cell because their ability to evolve is slowed by their need to interact with each other in the right way. In an earlier post, I asked: Who…

Last week I posted an image with two molecules (below the fold), one protein and one nucleic acid, and asked you about the probability of finding similar molecules in different species. You gave me some interesting answers.

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:
