A bunch of good places to look for genetics news articles
Greetings!
As you know, on Tuesday, you'll be turning in Assignment O, where you pick a topic having to do with genes, genetics, DNA, genetic engineering, genetic research, genomes, genomics etc. (Hey look! I just gave you a good list of search terms!). For assignment O, you'll turn in an explanation of the topic, why you think it's interesting, and citations for two news articles about that topic. (You'll be finding even more articles on the topic next week.)
To help you find articles, here are some good places to look:
- Search Google News or Yahoo News for any of the search terms above
- Science News, the weekly science magazine.
- Articles collected by the NPR science news show Science Friday.
- Biology news from Scientific American.
- Science Daily.
- Science stories from the New York Times. (Try the "browse topics" menu on the right - the "genetic engineering" topic has lots of good stuff!)
- Articles from the American Association for the Advancement of Science.

A good animation showing protein synthesis
Here's a good video of protein synthesis. Make sure you listen to the narration.
Another one, with more realistic molecule shapes and showing the process in real time, can be seen here.

The extra credit song...
...is called "That Spells DNA" by Jonathan Coulton and you can stream it for free (and it looks like you can download it for free, at least for now on his home page. Just look for DNA on the page.
Look ye here for notes
W27D2 notes, reprising yesterday's research. Enjoy, and don't forget to check the speaker notes for extra info.

Web Pages to Use for W27D1
Overview of Avery's work and the Hershey-Chase experiment.
Another overview of the same material.
A biography of Rosalind Franklin.
If you look at Dec. 11 and 12th in this blog, you'll find a nice overview of Chargaff's discoveries.
An extremely detailed online timeline can be found here.
And, last but not least, a summary timeline from PBS. This is a good one to look at if you're confused!

Mitosis movies!
No, not movies of the digits at the end of my feet - movies of cell division. All of them are speeded up: mitosis takes many minutes.
This one shows the spindle (green) that pulls the chromosomes (red) apart.
The fifth movie on this page is a movie showing multiple cells undergoing mitosis as a sea urchin embryo grows. The spindles show up as white.
Rat kidney cells undergoing mitosis are visible if you look for the heading "Chromosomes and the spindle" on this page, and then open the movie.
ANIMATIONS
A good animation of mitosis, with explanations, is here.
Here's a nice 3D animation, with a "zoom in" to the nucleus at the start (and ridiculous music).
A simplified, step-by-step animation (with a quiz afterwords) can be found here. Great if you're having trouble following the other animations.

A good site to explore
The University of Utah has a great site to reinforce your genetics learning. If you were confused by the lessons today or yesterday, you should check out the first two presentations on this page.
