Why do I love Cn3D? Let me count the ways. What does Cn3D do? (Hint: say "Cn3D" out loud). Seriously, Cn3D is a program that draws lovely pictures of molecular structures by using experimental data from techniques like X-ray crystallography and nuclear magnetic resonance spectroscopy. Surprisingly (to some), and in contrast to many bioinformatics programs, Cn3D is really easy and fun to use. Have you ever used programs like MS Office? Using Cn3D is at least 10 times easier. An added benefit is that you don't have to try and find old copies ... Read more
If we compare sections 1, 2, and 3, we see that section 2 matches very well in a number of different samples, and that there are differences between the sequences in sections 1 and 3. i-bed5846063bbebc59fa0a4516d917562-small_mito_mut.gif We also learn something about the ... Read more
Like biology, all bioinformatics is based on the idea that living things shared a common ancestor. I have posted, and will post other articles that test that notion, but for the moment, we're going to use that idea as a starting point in today's quest. If we agree that we have a common ancestor, then we can use that idea as a basis to ask some interesting questions about our genomes. For, example, we know that genomes change over time - we've looked at single nucleotide changes here and ... Read more
