BIOL 1115

Biology Laboratory I

0 Credits


In this five-day lab course, students perform experiments that illustrate the principles learned in BIOL 1113.

Delivery Methods

This course is offered in-person (laboratory, clinicals, practicum) in a laboratory setting.

Labs are held in either May, June or July at Thompson Rivers University, Kamloops, BC. Accommodation may be available at campus residences. TRU-OL reserves the right to cancel a lab section in the event the minimum student enrolment is not obtained by the registration dead-line.


Prior or concurrent registration in BIOL 1113 or equivalent is strongly recommended.


By the end of this course, students should be able to:

  • 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.

Required Text and Materials

Students will be required to print their own laboratory manual prior to their first day in class. Other supplies will be provided during the lab. For safety reasons, students must wear closed shoes. No open-toed shoes or sandals are permitted in the labs.


Students will receive a final mark out of 100. Students cannot miss more than two lab sessions or an incomplete grade will be assigned.

For safety orientation reasons, students are required to attend the first lab session.
