Cn3D

This five and half minute video introduces some of the basic skills for using Cn3D. Read more

Want to learn more about Parkinson's disease? See why a single nucleotide mutation messes up the function of a protein? I have a short activity that uses Cn3D (a molecular viewing program from the NCBI) to look at a protein that seems to be involved in a rare form of Parkinson's disease and I could sure use beta testers. If you'd like to do this, I need you to follow the directions below and afterwards, go to a web form and answer a few questions. Don't worry about getting the wrong answers. I won't know who ...

Over 2600 genetic diseases have been found where a change in a single gene is linked to the disease. One of the questions we might ask is how those mutations change the shape and possibly the function of a protein? If the structures of the mutant and wild type (normal) proteins have been solved, NCBI has a program called VAST that can be used to align those structures. I have an example here where you can see how a single amino acid change makes influenza resistant to Tamiflu®. This 4 minute movie below shows how we can obtain those aligned ... Read more
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. ... Read more
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-279383f2290486dd918584a6e0c70a95-caff3.gifI'm here to help to you make a merry mug with one of our favorite molecules. Yep, we're talking caffeine. 1. First, we'll go to ... Read more
