BIO 201: Cell Biology: Exam I Due: Monday, 16 February 2009, 9:00AM, Fisher 211 This is to be your OWN work, not a group effort. If you have ANY questions, please feel free to contact me. I am available in my office on Thursday, at extension x7431, or at home 413-528-4882, or on my cell 508-472-7527, or by email [email protected] . I will check my email and voice mail over the weekend, but please try several ways to contact me before depending on me retrieving your first message. Format: Written answers should be carefully crafted, using complete sentences and structured paragraphs. Type your work, and check your grammar and spelling. I don’t care about margins or line spacing, but make it readable and do your best to conserve paper. Diagrams should be carefully drawn and labeled, using color if it helps to convey information. 1. In the schematic diagram of a protein given below, label the strands linked together as a Beta sheet with a “B”, and the alpha helix/helices with an “a”. Is the Beta sheet parallel or antiparallel? Explain why. State whether this is a diagram of primary, secondary, tertiary, or quaternary protein structure. (10 points)

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
