BIOL 204 is not available for challenge.
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.
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
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
To receive credit for BIOL 204, you must achieve a course composite grade of at least “D” (50 percent), 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:
The midterm and final examinations for this course must be taken online with an AU-approved exam invigilator at an approved invigilation centre. It is your responsibility to ensure your chosen invigilation centre can accommodate online exams. For a list of invigilators who can accommodate online exams, visit the Exam Invigilation Network.

A print version of the eTexts may be available for purchase from the publisher through a direct-to-student link provided on the course website; you can also acquire the textbook on your own if you wish.
Home Lab Kit. All other learning resources will be available online. The home lab kit is non-returnable.
Special Course Features
The Home Lab Kit (non-returnable) supplies most of the materials used for the home labs. The student will, however, have to supplement the Home Lab Kit with some common kitchen items or supplies.
