APRIL was so much fun, that I thought I should find a molecule for May. I searched both the Gene database, the structure database, everywhere, without any luck. Finally, I decided to change the search and use the date instead of the name of the month. And here we have it, straight from PubChem. 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…

I love using molecular structures as teaching tools. They’re beautiful, they’re easy to obtain, and working with them is fun. But working with molecular structures as an educators can present some challenges. The biggest problem is that many of the articles describing the structures are not accessible, particularly those published by the ACS (American Chemical…

This morning I had a banana genome, an orange genome, two chicken genomes (haploid, of course), and some fried pig genome, on the side. Later today, I will consume genomes from different kinds of green plants and perhaps even a cow or fish genome. I probably drank a bit of coffee DNA too, but didn’t…

How do you go about researching a genetic disease? This multi-part series explores how digital resources can be used to learn about Huntingtin’s disease. Reposted and updated from the original DigitalBio. A bit of background Alice’s Restaurant is a movie with an unforgettable song that mostly revolves around Arlo Guthrie hanging out with his friends.…

This is a fun puzzle. The pink molecule is a protein and the other molecule is a nucleic acid.

How do you use science outside of the lab? People say that transferring knowledge and skills from one subject to another represents one of the highest levels of learning. They also say that it hardly ever happens. Perhaps this explains some of the more astounding things that we hear from Nobel Prize winners, like when…

The grocery store magazine covers all say that home made gifts are big this year. So I thought, some of you might like to channel your inner Martha Stewart and make gifts with a science theme. I’m here to help to you make a merry mug with one of our favorite molecules. Yep, we’re talking…

Irony in RNA: a puzzle

This structure is called a “kissing loop” and I find that name just a bit odd, given the source of the structure.

When purified, it glows with an unearthly light. You can’t go “chemical free” and try to escape it. It’s part of our bones and it forms the backbone of our DNA. A tool for good, a tool of war, essential for gardening, and infamous as a pesticide; phosphorus is truly an amazing element. Amazing too,…
