Course description and aims

The course will cover the structure and dynamics of cellular components, and the basic technologies for studying cells, including cell isolation, cell culture, and light and electron microscopy. Topics will include the details of subcellular compartments and the mechanism of macromolecule traffic system, signal transduction, cell cycle, apoptosis, and carcinogenesis. As an excellent molecular biology model, the life cycle of some viruses and bacteriophages will also be picked up.

The course aims to understand the basics of cell structure and function, which is essential for further learning of higher-order biological function and application for bioengineering.

Molecular Biology II is designed to be taken with Molecular Biology I and Biochemistry I and II. Students are advised to enroll in all four courses in order to receive optimal instruction.

Student learning outcomes

By the end of this course, students will be able to:
1. explain the techniques for cell isolation, culture of useful cells such as stem cells, and cell manipulation for genetics and reverse-genetics, and the microscope technologies to observe cell structure and dynamics including light, fluorescence, and electron microscopes.
2. explain the mechanism of intracellular traffic, including cytoplasmic-nuclear transport, endoplasmic reticulum, trans-Golgi network, lysosome, endocytosis and exocytosis, and signal transduction, including ligand-receptor biding, second messenger, phosphorylation cascade.
3. explain the cell cycle and its regulation by Cdk-cyclin, checkpoint, chromosome segregation, and cytokinesis.
4. explain the mechanism of apoptosis and carcinogenesis, such as the nature of cancer cells, oncogene, anti-oncogenes, and treatments.
5. explain the characterization and structure of viruses, and the life cycle of lambda phase and influenza virus.

Class flow

When necessary, in the first 10-15 min of each lecture, a summary of the previous lecture is given, followed by the main points of the day's lecture. In the last 10-15 min of each lecture, a quiz may be given to find out if students have learned the material given.
