- survey of major taxa, from viruses to animals
- Origins and Evolution of Life
- theories regarding the origins of life
- origin of prokaryotic and eukaryotic cells
- macroevolution, speciation and reproductive isolating mechanisms
- Introduction to Genetics
- mitosis and meiosis
- Mendelian Inheritance: theory and problems
- Non-Mendelian Inheritance: multiple alleles, sex linkage and multigenic inheritance.
- Molecular and Cellular Basis of Life
- chemistry of amino acids
- formation of primary, secondary, tertiary and quaternary structure of proteins.
- functions and mechanisms of action of enzymes
- functions and structures of DNA and RNA

- measurement of fermentation rate in yeast
Learning outcomes
Upon completion of this course, students will be able to:
- Understand and explain an understanding of the relationship between the biotic and abiotic components of the biosphere, their interactions and relationship to evolution.
- Use and demonstrate techniques for identifying plants and animals, including use of microscopes and dichotomous keys.
- Understand and explain the evolutionary relationships among major taxa.
- Understand and explain the relationship between genetics and evolution.
- Appreciate the scientific process, including the use of testable hypotheses.
- Explain cell division in plants and animals, and describe the significance of mitosis and meiosis to growth, development and reproduction.
- Solve monohybrid and dihybrid problems, and problems involving multiple alleles and sex-linked genes.
- Explain the molecular basis and significance of proteins, nucleic acids, lipids and carbohydrates, and their relationships to cellular respiration, photosynthesis and general metabolism.
- Explain how DNA and RNA replicate and code for proteins, and analyse problems using the genetic code.
- Understand and explain how genes interact with the environment, and the role of mutations, meiosis and fertilization in changing the genetic composition of populations over time.
- Discuss the mechanisms of evolution, and apply evolutionary concepts to the analysis of current environmental problems.
- Demonstrate the use of common laboratory equipment.
- Conduct simple directed experiments and explain the procedures and results.
- Understand and use biological principles in the discussion of current topics in Biology.
Means of assessment
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
| Evaluation | Marks |
| Class tests and assignments | 15-25 |
| Laboratory assignments and quizzes | 5-15 |
| Laboratory examination - final | 10-15 |
| Comprehensive examination - midterm | 25-35 |
| Comprehensive examination - final | 25-35 |
| TOTAL | 100 |
Notes:
1. Laboratory Experiments and Activities
Laboratory work will be assigned each week. The laboratory work must be completed in the week it is assigned. Laboratory experiments and assignments are a compulsory component of this course. A minimum of 50% of the laboratory experiments and assignments must be completed to receive a P or better in the course.
2. Examinations
There will be one midterm and one final examination. The final examination will cover the entire course. If the student achieves a better grade on the final exam than on the midterm examination, the midterm grade will be raised to equal that of the final examination.
Textbook materials
Students should consult the Douglas College Bookstore for the latest required textbooks and materials. For example, textbooks and materials may include:
Reece, J.B. et al., Campbell Biology. (Current Edition). Benjamin Cummings.
Douglas College produced manual: Biology 1310: Introduction to Biology.
