BIOL 1115: Biology Laboratory I
In this five-day lab course, students perform experiments that illustrate the principles learned in BIOL 1113.
Schedule: https://www.tru.ca/distance/courses/summer-science-lab-courses.html
Learning outcomes
- Use and understand the scientific method to study various biological processes.
- Use laboratory equipment, such as microscopes, glassware, spectrophotometers, and staining reagents, with care and proficiency.
- Learn to observe both microscopic and macroscopic details relating to structure and function.
- Learn to recognize and classify cells as prokaryotic versus eukaryotic, both plant and animal.
- Learn the basic structure of DNA, RNA and proteins through use of models.
- Learn the processes of replication, transcription and translation.
- Learn the stages and characteristics used to identify each stage of mitosis and meiosis.
- Learn the difference between karyotypes of males and females.
- Understand the causes and consequences of chromosome abnormalities and resulting karyotypes.
- Understand the basic Mendelian genetics (dominant and recessive characteristics and co-dominance) through monohybrid and dihybrid crosses.
- Understand sex-linked traits and how to analyze human pedigrees.
- Understand the light reaction of photosynthesis by creating the absorbance spectra and action spectra of various plant pigments.
