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 true. Back in March, when Nature Genetics published this paper ...
"Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!" - from Jabberwocky, by Lewis Carroll I'm certain that if we ever sequenced DNA from the frumious Bandersnatch it would match hypothetical and putative proteins. Why? Because we ...
What do you do when base-callers disagree? Okay DNA sequencing community, I want your help with this one. One of these sequences was called by phred and the other by the ABI KB base calling program. Which one should I believe? tags: Sometimes I open up files and do short ...
Razib inspired me to share some of the story behind why white people are considered derivatives. No red herrings, here! Lamason et. al. found a single gene that controls human skin color while studying pigmentation in zebra fish (1). These zebra fish had an unusual golden color that turned out ...
GenomeWeb reports that Rite Aid drug stores on the West coast are now selling kits for doing paternity tests. The kits are made by Sorenson Genomics in Utah. Sorenson Genomics calls it the " peace-mind-test." Really! Each kit contains a swab for collecting cheek cells from the inside of your ...
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 ...
One of my readers asked: Why does genome sequencing cost so much? My short answer is because it's big. But I thought it would be fun to give a better answer to this question, especially since I'm sure many of you are wondering the same thing. Okay, so let's do ...
Lots of bloggers in the DNA network have been busy these past few days writing about Google's co-founder Sergey Brin, his blog, his wife's company ( 23andme), and his mutation in the LRRK2 gene. I was a little surprised to see that while other bloggers ( here, here, here, and ...
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 ...
Sometimes asking a question can be a mistake. Especially when your question leads to more questions and having to question things that you didn't want to question, and pretty soon you begin to regret ever opening the file and looking at the data and asking the question in the first ...
Dave Robinson and Joann Lau from Bellarmine College in Kentucky are going to be describing their student project in a free webinar next Friday, May 16th. Their students clone GAPDH (Glyceraldehyde 3-Phosphate Dehydrogenase) genes from new plants, assemble the DNA sequences, and submit them to the NCBI. Here's an example ...
