Do mosquitoes get the mumps? Part V. A general method for finding interesting things in GenBank This is the last in a five part series on an unexpected discovery of a paramyxovirus in mosquitoes and a general method for finding other interesting things. In this last part, I discuss a ...
Have you ever wondered how to find things in the NCBI databases? Maybe you tried to find something but didn't know how it was spelled. Or maybe you tried to use a common name like "pig" or "deer" to find information in a database, not knowing that all the organism ...
It's pretty common these days to pick up an issue of Science or Nature and see people ranting about GenBank (1). Many of the rants are triggered, at least in part, by a wide-spread misunderstanding of what GenBank is and how it works. Perhaps this can be solved through education ...
No more delays! BLAST away! Time to blast. Let's see what it means for sequences to be similar. First, we'll plan our experiment. When I think about digital biology experiments, I organize the steps in the following way: A. Defining the question B. Making the data sets C. Analyzing the ...
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 ...
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 ...
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 ...
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 ...
In my last post, I wrote about insulin and interesting features of the insulin structure. Some of the things I learned were really surprising. For example, I was surprised to learn how similar pig and human insulin are. I hadn't considered this before, but this made me wonder about the ...
or is it just an idea that's ahead of the curve? Last week, I was stunned to discover at least 31 papers in an NCBI Gene database entry that were in the entry for the wrong gene. I wrote about this here, here, here, and here. Now, an oversight like ...
You might think the coolest thing about the Next Generation DNA Sequencing technologies is that we can use them to sequence long-dead mammoths, entire populations of microbes, or bits of bone from Neanderthals. But you would be wrong. Sure, those are all cool things to do, but Next Generation DNA ...
Instead of enjoying a sunny summer day today, or partying with SciBlings in New York, I'm staring out my window watching the rain. Inspiration hit! What about searching for August? Folks, meet the HFQ protein from E. coli. I found this lovely molecule by doing a multi-database search at the ...
In which we search for Elvis, using blastp, and find out how old we would have to be to see Elvis in a Las Vegas club. Introduction Once you're acquainted with proteins, amino acids, and the kinds of bonds that hold proteins together, we can talk about using this information ...
In a recent post, I wrote about an article that I read in Science magazine on the genetics of learning. One of things about the article that surprised me quite a bit was a mistake the authors made in placing the polymorphism in the wrong gene. I wrote about that ...
We'll have a blast, I promise! But there's one little thing we need to discuss first... I want to explain why I'm going to use nucleotide sequences for the blast search. (I used protein the other day). It's not just because someone told me too, there is a solid rational ...
