Your Task Explain what the source tells us about the historical period in which it was created. Paragraph 1: Explain the source State the main idea or message of the source. Identify two specific details that you see or read in the source. Explain how each detail supports your interpretation. Do not only list what you see. Explain what the details mean. Paragraph 2: Connect the source to history Include one specific facts from the course material. Explain how your fact connects to the source. Your fact must identify a specific person, law, event, organization, or movement that is not directly named or shown in the source.
Yоu аre studying а prоtein yоu cаll Unknown Protein 1 or UP1 in rat neurons. You believe mutations in UP1 may predispose people to Parkinson's Disease, so that wildtype UP1 may be neuroprotective. You have a rat model for Parkinson's Disease (PD rats), and you can culture neurons from PD rats and see markers of Parkinson's Disease. To test your neuroprotective hypothesis, you want to express wildtype UP1 in PD rat neurons. a. Starting with the UP1 protein sequence, name the procedure you will use to isolate a DNA fragment encoding UP1? b. How will you use the DNA from part a to express wildtype UP1 in cultured PD rat neurons (what do you need to do with the DNA from part a)? c. You raise an antibody against UP1. You want to use this antibody to: 1) identify the band that contains UP1 protein on a western blot, and 2) visualize the localization of UP1 protein within PD rat neurons. Is it possible to perform both of these approaches with this antibody? Provide a brief explanation of why (or why not).
