You are studying a protein you call 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).

Calculate the energy associated with one photon of UV-B radiation that has a wavelength of 300 nm. (h = 6.626 × 10⁻³⁴ J·s; c = 3.00 × 10⁸ m/s). Report your answer in joules using scientific notation and to three significant figures. Use the format 1 x 10^3 to report your answer.

You have identified a novel protein complex that forms a pore across the plasma membrane of a eukaryotic cell. The pore is made of five protein subunits, each of which contributes a membrane-spanning alpha helix to form the pore. Each alpha helix has hydrophilic amino acid side chains on one face of the helix and hydrophobic amino acid side chains on the opposite side.What is the likely arrangement of these five a helices in the membrane?

Study the visual primary source below. This may be a political cartoon, photograph, poster, advertisement, or other historical image. Write at least two full paragraphs. 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 fact 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.

An infant has an acute respiratory decompensation associated with sepsis on DOL 7. The VS are as follows: HR 158, RR (on HFJV), and BP  26/15 (20). Pulses +1/4, capillary refill 4 seconds. The urine output is decreased to 0.5 ml/kg/hr. Urinalysis does not show hematuria or proteinuria. The infant is given a normal saline bolus 10 ml/kg and started on dopamine at 5 mcg/kg/hr and the urine output improves to 1.5 ml/kg/hr. The most likely etiology of this type of acute kidney injury is:   A newborn with sepsis has hypotension, delayed capillary refill, and low urine output. After circulatory support, perfusion improves and urine output increases. Which mechanism most likely contributed to the initial oliguria?
