Genetics:
Head, Shoulders, Knees, and Toes
Why is an eye, an eye and a nose, a nose? Why do different cells create different kinds of tissues when all the cells in a single organism start out with the same set of instructions (aka DNA)?...Posted on October 10, 2006 11:41 AM • 0 Comments •
Time to Submit: Mendel's Garden Blooms Here on Sunday
Mendel's garden in Bruno, CZ, may be too far for physical travel, but you can still imagine what Mendel might have thought if he'd gotten a look at this version of his vision. Maybe I'm taking alliteration a little too...Posted on October 9, 2006 09:15 PM • 0 Comments •
White people are mutants
Razib inspired me to share some of the story behind why white people are considered derivatives. Reposted from the Classic Digital Bio. No red herrings, here! Lamason et. al. found a single gene that controls human skin color while studying...Posted on September 26, 2006 08:58 AM • 2 Comments •
Digital Biology Friday: The importance of being aerobic
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. We also learn something about...Posted on September 1, 2006 11:37 AM • 0 Comments •
Digital Biology Friday: All mutations are not alike
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...Posted on August 25, 2006 08:10 AM • 2 Comments •
Using HIV to prove some points about evolution, part IV
Did HIV become resistant to Atazanavir because of a genetic change? Was that genetic change inherited? Did HIV evolve? Can we explain why genetic changes at specific sites might help HIV escape the effects of the drug? Let's find out....Posted on August 23, 2006 10:06 AM • 0 Comments •
Using HIV to prove some points about evolution, part III

A lovely Sunday in the garden
August is the time when gardens look their best. Fruit becomes showy, flowers abound, and plants are large and plentiful. Mendel's Garden #4, currently blooming at The Inoculated Mind, is no exception. Evolgen pointed this out, so I had to...Posted on August 20, 2006 03:21 PM • 1 Comments •

Digital Biology Friday: Monkeying around with mitochondrial DNA
The past few Fridays, we've been comparing human mitochondrial DNA with the mitochondrial DNA of different apes. We started doing this here, where you can find directions for getting started. And, we've found some interesting things....Posted on August 18, 2006 03:43 PM • 2 Comments •
Using HIV to prove some points about evolution, part I.
When can a really bad virus be used to do something good? When we can use it to learn. The human immunodeficiency virus, cause of AIDS, scourge of countries, and recent focus of ScienceBlogs; like humans, evolves. As one of...Posted on August 17, 2006 11:59 AM • 2 Comments •
Digital Biology Friday: How similar are apes and humans?
During these past couple of weeks, we've been comparing mitochondrial DNA sequences from humans and great apes, in order to see how similar the sequences are. Last week, I got distracted by finding a copy of a human mitochondrial genome,...Posted on August 11, 2006 01:14 PM • 5 Comments •
Waxing lyrical about that stuff in our ears
It's hard sometimes when you're out of synch with the rest of the world. While my fellow ScienceBloggers have been obsessing about breasts, I've been really amused by the genetics of ear wax. Eh, what's that you say? Yes, it's...Posted on August 10, 2006 02:30 PM • 3 Comments •
Digital Biology Friday: Hey, who moved my DNA?
Last week, we decided to compare a human mitochondrial DNA sequence with the mitochondrial sequences of our cousins, the apes, and find out how similar these sequences really are. The answer is: really, really, similar. And you can see that,...Posted on August 4, 2006 01:39 PM • 3 Comments •
Digital Biology Friday: That was no ape, that was my brother!
We've had a good time in the past few last weeks, identifying unknown sequences and learning our way around a GenBank nucleotide record. To some people, it seems that this is all there is to doing digital biology. They would,...Posted on July 28, 2006 08:00 AM • 0 Comments •
Hang on, just let me make a quick clone fall
