Two teenagers, Kate Stoeckle and Louisa Strauss, carried out their own science project over the past year. They visited 4 restaurants and 10 grocery stores and gathered 60 samples of fish and sent them off to the University of Guelph to get sequenced. I like this story. One of my former students did a project…

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…

What are you learning in school?

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. Plus, since GAPDH is a…

Over 2600 genetic diseases have been found where a change in a single gene is linked to the disease. One of the questions we might ask is how those mutations change the shape and possibly the function of a protein? If the structures of the mutant and wild type (normal) proteins have been solved, NCBI…

In the class that I’m teaching, we found that several PCR products, amplified from the 16S ribosomal RNA genes from bacterial isolates, contain a mixed base in one or more positions. We picked samples where the mixed bases were located in high quality regions of the sequence (Q >40), and determined that the mixed bases…

I think all of us; me, the students the OO advocates, a thoughtful group of commenters, some instructors; I think many of us learned some things that we didn’t anticipate the other day and got some interesting glimpses into the ways that other people view and interact with their computers. Some of the people who…

Okay OpenOffice fans, show me what you can do. Earlier this week, I wrote about my challenges with a bug in Microsoft Excel that only appears on Windows computers. Since I use a Mac, I didn’t know about the bug when I wrote the assignment and I only found out about it after all but…

Here’s a fun puzzler for you to figure out. The blast graph is here:

Do different kinds of biomes (forest vs. creek) support different kinds of bacteria? Or do we find the same amounts of each genus wherever we look? Those are the questions that we’ll answer in this last video. We’re going to use pivot tables and count all the genera that live in each biome. Then, we’ll…
