Exams and grading policies Three exams during the semester and a comprehensive final  ­ see syllabus for dates. Exams will include short answer essays. No curve  ­ you know where you stand at all Umes. Challenges to test quesUons must be in wriUng with an explanaUon of why you believe your answer is correct.

The hourly exams will count for 100 points, and the final exam will count for 150 points, for a maximum of 450 points. Grades will be assigned on the following scale: A = 405 to 450 points (≥90%) B = 360 to 404 points (≥80%) C = 315 to 359 points (≥70%) D = 270 to 314 points (≥60%) F = 269 or fewer points (<60%) Tips for how to do well in Biol 213 1)  Read the chapter one to two days before the lecture, trying to explain the material to yourself. 2)  Close the book and without referring to notes, “teach” the material to yourself, a friend or an imaginary audience. 3)  Make notes on things that you don’t understand and listen to us explain it in class. 4) If you sUll don’t understand a concept, ask a quesUon in class! 5)  Aoer the lecture, “teach” the material to yourself again to solidify what you learned in the book and lecture. 5 8/29/11 Exam 1 is on Tuesday, Sept 20th What will you learn by studying Cell and Molecular Biology? •  Cells are the fundamental unit of life •  All cells have similar chemistry •  MechanisUc understanding of cellular funcUon and dysfuncUon 6 8/29/11 The Cell Theory Robert Hooke Anton van Leeuwenhoek Algae Spirogyra (1674) Cork (1665) The Cell Theory In 1838, Schleiden & Schwann proposed two tenets of the cell theory: 1. All organisms are composed of one or more cells. 2. The cell is the structural unit of life. 1855, Virchow proposed a third tenet of the cell theory: 3. Cells can only arise by division from a preexisUng cell. 7 8/29/11 Pasteur Experiment (1864) Boil ub Inc e at Strong support for germ theory and against spontaneous generaUon – Omne vivum ex ovo (All life is from eggs) DNA Replicaaon 8 8/29/11 an sp or t Membrane Energy Tr Communicaaon Cytoskeleton DNA (blueprint) Uo n crip rans NA TR m on slaU Tran Proteins (executors) Replicate & Repair Three Domains of Life 9 8/29/11 an sp or t Membrane Energy Tr Communicaaon Cytoskeleton DNA (blueprint) on ripU ansc A Tr RN m on slaU Tran Proteins (executors) Replicate & Repair 10 ...
