http://www.ScienceTutorOnline.com This week's video is an excerpt from an online biology class I'm teaching. I'm trying to provide some historical context for genetics. I deeply admire James Watson and Francis Crick (and love Watson's sharp wit in his books) but the discovery of the structure of DNA was really a long process that took more than a century.
About halfway through the video there's a reference to Photo 51, the radio crystallography picture that gave the game to Watson and Crick. They had the intelligence and creativity to connect all the dots, but it's sad that Rosalind Franklin didn't get more recognition before her untimely death. You can view the photo here:

By the way, I'm putting together an online AP Biology class if there's enough interest. Sleep as late as you need, study when you want, take the exam and you've just saved $500 in tuition.
There will be more classes as I get other teachers on board. If you're interested as a student or a teacher, send me a message or go to http://www.ScienceTutorOnline.com
Повторяем попытку...
