Overview
Biology 204: Principles of Biology I is an introductory course in general biology for BSc. students and the first of two introductory biology courses that will prepare students for second-year biology courses. It is designed to help students learn more about the nature of life, topics include the nature of science, enzymes, cells, cellular respiration, photosynthesis, classical genetics, DNA structure and replication, gene structure and expression, regulation of gene expression, and molecular biology.
Outline
After an introduction about the nature of science, BIOL 204 covers four units:
- Unit 1: Cell Biology
- Unit 2: Bioenergetics
- Unit 3: Classical Genetics
- Unit 4: Molecular Genetics
The material covers the following chapters in the course textbook:
- Chapter 1: Light and Life
- Chapter 2: The Cell: An Overview
- Chapter 3: Defining Life and Its Origins
- Chapter 4: Energy and Enzymes
- Chapter 5: Cell Membranes and Signalling
- Chapter 6: Cellular Respiration
- Chapter 7: Photosynthesis
- Chapter 8: Cell Cycles
- Chapter 9: Genetic Recombination
- Chapter 10: Mendel, Genes, and Inheritance
- Chapter 11: Genes, Chromosomes, and Human Genetics
- Chapter 12: DNA Structure, Replication, and Organization
- Chapter 13: Gene Structure and Expression
- Chapter 14: Control of Gene Expression
- Chapter 15: DNA Technologies
- Chapter 16: Genomes and Proteomes
Learning outcomes
Upon successful completion of this course, you should be able to
- explain that biology is the science of living organisms based on the scientific method, which is a unique method of exploration that uses open-ended inquiry
- describe cells as the basic units of life, explain cell theory, and point out the fundamental differences between pro- and eukaryotes, as well as the roles of membranes and organelles
- explain that all organisms are dependent on a steady supply of energy and that respiration and photosynthesis are some of the major metabolic pathways
- describe how enzymes play a crucial role as catalysts in all processes of the cell
- describe the key concepts of classical genetics including cell division, gene recombination and Mendelian principles as well as chromosomal theory
- describe in detail DNA structure and replication, as well as gene expression by transcription and translation as fundamental processes of molecular biology
- explain why gene expression requires a tight regulation at several levels and point out some examples for modern DNA technologies
Evaluation
To receive credit for BIOL 204, you must achieve a course composite grade of at least , a minimum of 50 percent for the composite lab activities, and a grade of at least 50 percent on the final examination. The weighting of the composite grade is as follows:
| Activity | Weight |
| Assignment 1 | 9% |
| Assignment 2 | 9% |
| Assignment 3 | 9% |
| Assignment 4 | 9% |
| Lab Report | 9% |
| Essay | 8% |
| Lab Results | 7% |
| Midterm Exam | 15% |
| Final Exam | 25% |
| Total | 100% |
The midterm and final examinations for this course must be requested in advance and written under the supervision of an AU-approved exam invigilator. Invigilators include either ProctorU or an approved in-person invigilation centre that can accommodate online exams. Students are responsible for payment of any invigilation fees. Information on exam request deadlines, invigilators, and other exam-related questions, can be found at the Exams and grades section of the Calendar.
