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…

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…

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…

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, but I don’t think that’s…

Right or wrong, the word “dopamine” always conjures up images in my head of rats pushing levers over and over again, working desperately hard to send shots of dopamine into their tiny little rodent brains.

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 yesterday. The other thing that…

In its simplest sense, we imagine that learning occurs through a series of positive and negative rewards. Some actions lead to pleasure, others to pain, and it seems reasonable to expect that people will repeat the actions with pleasurable results and avoid those that ended in pain. Yet, we all know people who aren’t deterred…

Have you ever wondered what kinds of viruses can be found in human waste? Mya Breitbart and team have been sequencing nucleic acids from fecal samples in order to find out. You might expect that we’d find viruses that infect humans or viruses that infect the bacteria in our gut. I wouldn’t have expected to…

I’m in Berkeley right now at the annual Bio-Link Summer Fellows forum. We’re getting to hear talks from people in the biotech industry, listen to enthusiastic instructors describe their biotech programs and ideas, and try out new educational materials. Yesterday, two speakers (Damon Tighe and Jason Baumohl) from the Joint Genome Institute in Walnut Creek,…

I got my copy of “A short guide to the human genome” by Stewart Scherer today from Cold Spring Harbor Laboratory Press (2008, ISBN 978-087969791-4). Usually, I would wait until after I’ve read a book to write a review, but this book doesn’t require that kind of study. As soon I skimmed through it and…
