Part IV. Assembling the details and making the case for a novel paramyxovirus This is the fourth in a five part series on an unexpected discovery of a paramyxovirus in a mosquito. In this part, we take a look at all the evidence we can find and try to figure out how a gene from a virus came to be part of the Aedes aegypti genome.
Part III. Serendipity strikes when we Blink In which we find an unexpected result when we Blink while looking at the mumps polymerase. This is the third in a five part series on an unexpected discovery of a paramyxovirus in mosquitoes. And yes, this is where the discovery happens. I. The back story from the genome record II. What do the mumps proteins do? And how do we find out? III. ... Read more
Part II. What do mumps proteins do? And how do we find out? This is the second in a five part series on an unexpected discovery of a paramyxovirus in mosquitoes, and a general method for finding interesting things. I. The back story from the genome record II. What do the mumps proteins do? And how do we find out? III. Serendipity strikes when we Blink. IV. ... Read more
Part I. The back story from the genome record Together, these five posts describe the discovery of a novel paramyxovirus in the Aedes aegyptii genome and a new method for finding interesting anomalies in GenBank. I. The back story from the genome record II. What do the mumps proteins do? And how do we find out? III. Serendipity strikes when we Blink. IV. ... Read more
One of the things that drives me crazy on occasion is nomenclature. Well, maybe not just nomenclature, it's really the continual changes in the nomenclature, and the time it takes for those changes to ripple through various databases and get reconciled with other kinds of information. And the realization that sometimes this reconciliation may never happen. One of the projects that I've been working on during the past couple of years has involved developing educational materials that use bioinformatics tools to look at the isozymes that metabolize alcohol. As part of this ... Read more

Ancestry tests aren't just for humans anymore. We went to Petco this weekend to buy dog food and found brochures for doggy DNA testing. Now, those of you with dogs of uncertain parentage need puzzle no longer. According to Petco, their SNP test (what is a SNP?) can identify over 100 different breeds and they'll tell you which breeds are represented in your dog and whether your dog's breeding is mixed (or pure). ...

This the third part of case study where we see what happens when high school students clone and sequence genomic plant DNA. In this last part, we use the results from an automated comparison program to determine if the students cloned any genes at all and, if so, which genes were cloned. (You can also read part I and part II.) Did they clone or not clone? That is the question. ... Read more

This the second part of three part case study where we see what happens when high school students clone and sequence genomic plant DNA. In this part, we do a bit of forensics to see how well their sequencing worked and to see if we can anything that could help them improve their results the next time they sequence. How well did the sequencing work? Anyone who sequences DNA needs to be aware of two kinds of problems that afflict their results. We can divide these into two ... Read more
What happens when high school students clone and sequence genomic DNA? Background DNA sequencing is a wonderful tool for discovery and a great technique for getting students involved in molecular science. This fall, Bio-Rad will officially begin selling their DNA cloning and sequencing kit. Now, students across the country will have the tools in hand to begin their own projects cloning and sequencing plant genes. Of course, without bioinformatics there's no way to know what's been cloned or sequenced. This is where we come in. As part of an ... Read more
Are you curious about Second Life? Next week you can satisfy your curiosity and learn about the personal genomics frontier at the same time. Bertalan Meskó announced that Erin Davis (science writer) and Joyce Tung (human geneticist) from 23andMe will be giving a presentation next week in Second Life on personalized genetics. As travel costs rise and traveling becomes harder, I think we'll see many more things happening in alternative places like Second Life. ... Read more
