Upon completion of this course, students will:
- Understand and be able to explain the relationship between genetics and evolution.
- Be able to explain cell division in plants and animals, and to describe the significance of mitosis and meiosis to growth, development and reproduction.
- Be capable of solving monohybrid and dihybrid problems, and problems involving multiple alleles and sex-linked genes.
- Be able to explain the molecular basis and significance of proteins, nucleic acids, lipids and carbohydrates, and their relationship to cellular respiration and photosynthesis and general metabolism.
- Be able to explain how DNA and RNA replicate and code for proteins, and analyse problems using the genetic code.
- Understand and be able to explain how genes interact with the environment, and the role of mutations, meiosis and fertilization in changing the genetic composition of populations over time.
- Be able to discuss the mechanisms of evolution, and to apply evolutionary concepts to the analysis of current environmental problems.
- Be capable of conducting simple directed experiments and explaining the procedures and results.
- Understand and be able to use biological principles in the discussion of current issues.
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:
|Class tests and assignments||15-25|
|Laboratory tests and assignments||5-15|
|Laboratory examination - final||10-15|
|Comprehensive examination - midterm||25-35|
|Comprehensive examination - final||25-35|
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.
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.
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 1210: the Organism.
