Document Summary

The primary goal of bio a01 is to provide students with the strong foundation needed to become a successful biologist. Bio a01 is a lecture and laboratory course designed to encourage students to think broadly and critically about some major areas of study in biology (eg. evolutionary biology, cell biology and. Bio a01 consists of 36 lectures (3 x 50 minute lectures per week) and five labs (one. 3-hour lab practical every two weeks throughout the term). There are three modules consisting of 12 lectures per module. The first module will examine evolution as the framework in modern biology, and topics such as population, genetics, cladistics and speciation. An appreciation for the diversity of life is emphasized throughout this course with emphasis on prokaryotes, viruses/prions and protists. The second module of the course will introduce students to cell structure and then explore the principles of energetics and cellular metabolism, using respiratory and photosynthetic pathways as two important examples.

Cancer biologists use principles of evolution to understand the development of tumors. A population of cells can obtain a mutation after exposure to a carcinogen. In some of the cells, the mutation is not repaired by the cell’s DNA repair machinery and is retained in the genotype. Only a fraction of the cells retaining the mutation become cancerous and only a fraction of those cells have the ability to form a tumor – cells that grow much faster than normal body cells. From the perspective of a tumor-causing cell, what evolutionary processes are at work? From the perspective of the body harboring these tumor cells, what evolutionary processes are at work?
