COURSE OBJECTIVES

            The main objective of the course is to develop an understanding of how the major structures and biosynthetic activities of cells function and how they are coordinated and regulated.  We will first define the physical and chemical nature of cellular components and place them in their physical and evolutionary context.  The progression of topics on cellular function will be arranged in a “nucleus outwards” scheme.  Nucleic acids and their direction of protein synthesis will be considered in terms of structure and information flow. Membrane-based compartments will be studied in terms of their transport and bioenergetics functions. Finally the coordination of genome- and membrane-based regulatory processes will be addressed by examining cell-cell signaling processes.  Developing a sound conceptual basis for understanding these processes will require achieving a second objective of having students learn and apply strategies for independent inquiry and problem solving related to this material.

                                                                      Policies

Attendance:  Attendance will not be taken after the class rolls are corrected, but you will be asked to sign in every day.  You are responsible for all material presented in the class.  If you are not in class for an extended period, please let us know why and how you intend to get caught up.

Academic Integrity: All work for this course will be subject to the academic integrity policy of Trinity University.  If you are in any doubt about the application of policy to specific assignments, ask before proceeding.

Readings:  The lectures will assume that you have already done the readings assigned, and they may not make much sense if you have not. The point of the readings is to allow you to listen to the lectures without having to take copious notes; you should already understand the basics and not have to write them down again.  We recommend that you reread the material soon after the lecture to identify the strongest links between lecture and text.  We also recommend that you bring your book (or the TakeNote supplement) to class to follow the presentation and interpretation of figures from it.

Office Hours:  Formal times and locations are provided below.  Check for us in our offices first followed by our research laboratories.  Please make an appointment when you need another time.  If all else fails, contact us by electronic mail (brushing@trinity.edu & jshinkle@trinity.edu). 

                                    Location                                  Days                            Hours

Web site:  There will be a web site for this course. We will give you the URL once the site is up and has some content on it.  This web site is a work in progress and is meant to be a supplementary student resource and teaching tool.  Please do not utilize this site as your primary source for class materials.

Exams:  Exams will cover material from lectures and readings.  Exams will be of the short answer and short essay variety.  Three exams will be held on the evening of the day they are scheduled at 8 PM, and will be limited to 2 hours.  Students with a legitimate time conflict will be given the exam at an alternate time, preferably within 2 days of the scheduled exam.  If at all possible, notify us of illnesses or other emergencies before the exam.  A fourth term exam will be held during the class hour.  This exam will have a “takehome” component.  The final exam will be "semicumulative".  It will cover some material from all parts of the course, but will focus on the most recent material.  The final will be weighted according to each student's best interests; it can count as 100 or 200 pts, (300 pts in special cases).  For the fouth exam, and the Final, there will be 30 point take-home components (added to the in-class exam score), due as specified below.  Previous years' exams will be on reserve in the library.    

"Thought questions" will be assigned as homework before the first two exams. The first few will give you an idea of what kind of questions to expect and the scoring we use on exam questions.  If you do not turn in an assigned question, or get a low score on your answer, you may replace that score by attending a biology research seminar approved by Dr. Rushing or Dr. Shinkle (the Biology Departmental seminar, Mondays, 4 PM, 149 CLS, or equivalent), and writing a one page summary of its content.  You may do this for up to 2 thought questions.  Scoring on thought questions replaced with seminar summaries will be as follows: adequate summary, one or more key points missed – 7 points; good summary – 8 points; good summary with some perceptiveness about secondary points made by speaker – 9 points; very good summary relating ideas from lecture to specific material covered in Biol. 2320 – 10 points.

“Lecture Questions”: At selected points in lectures, where we know there should be questions, we will select a student at random, and request that she/he ask a question appropriate to the material just covered.  If the selected student declines to ask a question at that time, she/he must submit a question in writing before the next class period.  A good question, asked at any time, will make the student immune from selection.

Grading:  There are no preset cutoffs for specific grades, nor a specific curve applied.  We will grade individual questions, and take off points for incorrect or absent information.  Answers that are vaguely correct but subject to many other interpretations may not be given full credit.  Grammar and spelling must be intelligible, but they do not have to be perfect.  After totaling exam scores, we will read exams to assess the overall quality of the answers, and set approximate cutoffs accordingly.  Final course grades will take in to account such factors as a pattern of improvement and anomalous performance on a single exam.  The grading philosophy of the course is that we expect to give 10-20% A's, 40-50% B's and 30-50% C's and below.

Course work graded:

            Exam 1                                                             100 pts
            Exam 2                                                             100 pts
            Exam 3                                                             100 pts
            Exam 4                                                             130 pts
            Final                                                                 130 or 230 pts

            Thought questions                                              40 pts  

            Total                                                                 600 or 700 pts
