Description
In the past I had this assignment follow the lab on macromolecules, but in order to give folks even more time for kits to arrive, I switched things up a bit. Now you will learn about macromolecules AFTER this assignment. Just please note that DNA is a macromolecule. It is specifically a nucleic acid (RNA is the other nucleic acid).
Keep in mind that we didn’t always know what DNA looked like. Discovered in 1869, it was not until the 1950’s that we learned what it actually looked like. Everyone at some point in their lives is taught that Watson and Crick discovered the double helix structure of DNA, but folks, this is one of those not so proud moments in the history of science.
1) READING: Check the index of your textbook for “Rosalind Franklin” and read up, if she is there, it will only be a page at best. Here is an article from Science Mag about her: https://www.nature.com/scitable/topicpage/rosalind-franklin-a-crucial-contribution-6538012/
2) WATCH VIDEO: The NOVA video is an hour but it is good! You can certainly pause the video and pick up again at another time so no worries if you cannot carve out one full hour. https://vimeo.com/12471144
3) WATCH VIDEO: DNA/Chromosomes animation: It is a super short animation to help to envision DNA in and how it all fits into the nucleus. https://www.biointeractive.org/classroom-resources/how-dna-packaged
4) Watch this 17 minute HHMI video on The Double Helix. It gives you the history of discovering the structure and a look at the personalities involved. https://www.biointeractive.org/classroom-resources/double-helix
5) RESPOND: Please write about Rosalind Franklin and the infamous Photo 51. Your response should be no less than 2 pages and in typical 5 paragraph format (introduction, 3 supporting points and a closing). It should be double-spaced, font size 12, time new roman and have 1 inch margins. Include literature cited in CSE format. Here is a link to a CSE citation generator: https://www.citationmachine.net/council-of-science-editors. The literature cited should be on a separate page and does NOT count towards the two pages. It should include at the very least your textbook, the science mag article and the NOVA video.
