DNA+History+Project

See the Student Timelimes 2011 __Assignment Instructions__ In 1863 Mendel published his work on inheritance but it was perceived as a paper on hybridization and little attention was paid to it until the 1900 (Darwin never read his copy of the paper even though it was on his shelf and would have answered so many of his questions). In the 1900’s scientists were trying to find some way to explain discontinuous inheritance of traits (i.e. blue  eyed child born to brown  eyed parents) and Mendel’s work was rediscovered. In the ensuing 100+ years we figured out what traits really are (proteins and protein interactions), and how DNA works as a mechanism for inheritance. It’s a history full of puzzles, competition, sadness, joy, romance, and luck.

 Your job will be to create an interactive web timeline of this history. You will first use this document as a way to collaborate on your research, collecting text,IMAGES, video links, etc. As you progress be sure to include answers to the following questions: There are resources to get you started on our class __wiki__ , including excellent PowerPoint's. For every decade I’d also like you to include a significant historical event/period in the USA and Internationally (could be a scientific breakthrough, political event, etc.). Site sources using easybib (under more in dropdown menu at the top). Have Fun!
 * 1) How did we figure out that chromosomes were key to inheritance and related to Mendel’s laws?
 * 2) How did we figure out what chromosomes are made of?
 * 3) Why did scientists think proteins must be the hereditary material and not DNA
 * 4) What series of experiments convinced scientists that DNA was the hereditary material (many experiments spanning decades). What new puzzles did this generate.
 * 5) How did we figure out the shape of DNA and how did this help us understand how it worked?
 * 6) How did we figure out how DNA copies itself and works as a code for proteins?
