viral genomes

I was pretty impressed to find the swine flu genome sequences, from the cases in California and Texas, already for viewing at the NCBI. You can get them and work them, too. It's pretty easy. Tomorrow, we'll align sequences and make trees. Activity 3: Getting the swine flu sequence data 1. Go to the NCBI, find the Influenza Virus Resource page and follow the link to: 04/27/2009: Newest swine influenza A (H1N1) sequences. 2. You'll see a page that looks like this: Each column heading is a name of a segment of the influenza genome. You can see there are eight of these. Each segment…

Let's play anomaly! Most of this week, I've written about the fun time I had playing around with NCBI's Blink database and finding evidence that at least one mosquito, Aedes aegypti, seems to have been infected at some point with a plant paramyxovirus and that the paramyxovirus left one of its genes behind, stuck in the mosquito genome. During this process, I realized that the method I used works with other viruses, too. I tried it with a few random viruses and sure enough, I found some interesting things. You've got a week to give it a try. Let's see what you find! The method is…
