Cell and Molecular Biology I

7.5

A) Admitted to the bachelor programme in biology at the University of the Faroe Islands, and following the normal study progression or B) Students following single courses need to have sufficient background in general, organic chemistry, and biochemistry, like: 3512 General and inorganic chemistry; 3513 Organic chemistry; 3514 Biochemistry.

To provide the students with knowledge of cell structure and function, organelles, growth and cell cycle, and cellular and molecular interactions.

Structure of cells. Structure and function of organelles. Functions of DNA, RNA and proteins. Gene expression. Intracellular transport. Intercellular and intracellular communication: Hormones, growth factors, signal transduction. Genomes. Cell cycle and division. Evolution. Organization of tissues. Stem cells. Cancer. Laboratory demonstrations of cell culture, and laboratory exercises elucidating some cellular processes and some methods in cell biology, including use of light microscopy and epifluorescence microscopy.

Lectures. Problem solving (some of the exercises include obligatory submission). Student presentations. Laboratory demonstrations and exercises with reports (obligatory).

On completion of the course, the successful student should be able to: 1. Describe the structures of eukaryotic cells and their major organelles. 2. Describe and discuss the most significant functions of the major organelles. 3. Describe regulation of proteins, chromatin structure and gene expression. 4. Describe in considerable detail the main parts of the cytoskeleton and its constituents. 5. Give a basic overview of methods used in analyzing genes and genomes. 6. Describe experimental methods and tools for studying the cytoskeleton, some membrane-enclosed organelles and their trafficking pathways, including basic theoretical background of the methods (for example: fluorescence or antibodies). 7. Perform some simple experiments that can elucidate the cytoskeleton, organelles and their trafficking pathways. 8. Examine and discuss evolution of genes and genomes at basic levels. 9. Examine and explain structure, functions and components of cellular membranes, including transport of molecules and ions across membranes and the importance of such transport in cell homeostasis and neuronal signaling. 10. Describe and categorize cellular signaling pathways, including the transfer of a stimulus across a cell membrane, and how the stimulus is propagated to its effector, it be an enzyme or one or several genes. 11. Describe and explain all parts of the cell cycle, including mitosis; give basic review over the regulatory mechanisms of the cycle, and mechanisms for controlled cell death. 12. Describe two major types of tissues (connective and epithelial tissues), the concept of cellular communities and their organization (like communication between cells and the adhesion between cells), and show how stem cells maintain and renew tissues. 13. Contrast cancer cells and normal cells, and show how cancer behaves and disobeys the "rules" of the normal cellular community. 14. Connect and combine information from different parts of the present curriculum. 15. Connect and combine information from the present curriculum with those of previous courses, in particular biochemistry.

Combination of 1) accepted obligatory exercises and obligatory laboratory report and 2) graded written examination. 1) The obligatory exercises and laboratory report must be delivered within the specified deadlines. The answers and report must be accepted (no grading) by the instructor. 2) Four-hour written examination. No auxiliary materials allowed, except for electronic calculator. NVD computer available for writing. When the laboratory reports have been accepted, they are also valid in case of re-examination.
