Required Text: The World of the Cell, 6th  Edition, by Becker, Kleinsmith and Hardin

Recommended Text: Biology, 5th Edition, by Neil Campbell, or equivalent introductory biology text

 

Course Description: This is an introductory course in cell structure and function. It is intended for Biology majors, and covers such topics as chemical composition of cells, molecular structure and function of organelles, and the basic biochemistry underlying cellular behavior. Introductory college courses in biology and chemistry are prerequisites for this course.

 

Aims: To provide an understanding of the fundamental mechanisms of cellular function and to develop critical thinking skills in the context of modern cell biology.

 

Learning outcomes/objectives: At the end of this course, students should understand:

 

·         The structure, assembly, and function of cellular membranes, nucleic acids, and proteins

·         How proteins are sorted in eukaryotic cells

·         How metabolic energy is generated in cells

·         How chemical signals are generated, dispersed, and interpreted by cells

·         The structure and function of the cytoskeleton

·         The molecular mechanisms responsible for cell division, and how they are regulated

·         How to use common analytical tools and molecular methods to solve current problems in cell biology

 

Recitation Sections: All students will be required to attend weekly recitation section. These recitations are designed to clarify subject matter covered in lecture, practice answering exam-type questions, and apply the subject matter to real-world problems in biology. Sections will be taught by graduate teaching assistants, with help from undergraduate students who have completed this course in previous years.

 

Computer accounts: Outside of office hours, the best way to contact the instructor is through electronic mail (email). All students should have email accounts. 

 

Course web site: There is a web page to support this course. There you will find course announcements, a copy of the course syllabus, and links to relevant web pages. This web page can be found at: http://www.rpi.edu/~ploppg/BIOL2120.html

 

Instructor’s Responsibilities: 1) To be prepared for each lecture, 2) To present the most important information from assigned reading in a clear and concise fashion, 3) To be available outside of class to answer questions, 4) To reply to electronic mail promptly, and 5) To return exams in a timely fashion.  The instructor will not post lecture notes or distribute past exams. 

 

Student’s Responsibilities: 1) To be prepared for each lecture and each exam, 2) To seek assistance from the instructor when appropriate, 3) To check electronic mail regularly, and 4) To bring a #2 pencil and a photo ID to all exams.

 

Teaching Philosophy: Cell Biology is a core course for all Biology majors because the cell is the fundamental unit of life.  All biological processes, from virus replication to bird migration to gymnosperm evolution, arise as a direct consequence of basic cellular mechanisms. Cell biology is therefore a study of the mechanism of life.  Because this course represents a significant stage in undergraduate training in biology, it is assumed that students in this course will ask deeper questions than, “What do I need to know to get an A?”  Instead, students should ask themselves, “What should I be learning to advance my career as a biologist?” You will be expected to think in this course, not just memorize. I will provide you the tools to understand basic cellular functions, and will work with you to create a positive learning environment. To make the most of this course, however, you must provide the motivation, and do the work. My job is to help you learn cell biology; your job is to want to learn it.

 

Attendance Policy: Attendance in lecture is not required, but is strongly encouraged. Attendance in recitation sections and laboratory sections is required.

 

Grades: For the lecture portion of the course, grades will be computed from performance on three midterm exams (10%, 20%, and 30%, respectively ), and one comprehensive final exam (40%). Final grades will be computed from lecture (60%), recitation (5%) and laboratory (35%) scores, and will be based on a standard percentage scale (A=100-88%, A minus=87-85%, B plus=84-82%, B=81-73%, B minus=72-20%, C plus=69-67%, C=66-63%, C minus= 62-60%, D plus=59-57%, D=56-50%, F=49% or lower) but may be curved or otherwise adjusted at the discretion of the instructor. Thus, scoring 70% in lecture, 85% in recitation, and 90% in lab will result in a grade of B: (70 x .60) + (85 x .05) + (90 x .35) = 78%.

 

Mid-semester assessment: By week 7 in this course (2/25-2/28), students will have received four graded quizzes, one graded midterm exam, plus feedback from the laboratory instructor (Professor George Edick).

 

Makeup Exams: Midterm exams may be taken as makeup exams if arranged prior to the test date and approved by the instructor.  The format of these exams may differ significantly from the standard exams.  No makeup exam will be given for the Final Exam. No extra credit assignments will be given.

 

Academic Dishonesty: Academic dishonesty will not be tolerated in this course. A complete statement on academic dishonesty can be found in the current Rensselaer Handbook of Student Rights and Responsibilities. Further information can be found at http://www.rpi.edu/dept/doso/handbook.html. If you have any questions, or require clarification on the policy, please feel free to speak with us.

 

Disability: Students requesting support must contact Disabled Student Services at 276-2746 (email:hamild@rpi.edu).
