Molecular Biology

About the Program

Molecular Biology is an interdisciplinary science that draws its major themes from biochemistry, cell biology, and genetics. Its emphasis is on the structure, chemistry, and functions of nucleic acids and focuses on the biochemical basis of cellular genetics.


Honours Bachelor of Science

Program Options


After completing your first year, you'll be asked to confirm what program(s) you wish to study – your Programs of Study. They can be integrated in unique ways to obtain your U of T degree, but must be one of the following three combinations: one Specialist; or two Majors; or one Major and two Minors. You don't need to worry about that now, but if you'd like to learn more about this process, watch our handy video (7 min).

Admission Requirements

You apply to an admission category, which is a collection of similar programs. Once you've accepted an offer of admission to our campus, we go into greater detail about specific program and course selection options.

At the end of your first year, you will choose your program(s), which means that your first year is an excellent opportunity to explore the full breadth of offerings.

Regardless of what you study, remember that you will receive a prestigious University of Toronto degree when you graduate that tells everyone that you are ranked among the best in the world!

Discover Your Potential

Rachel Stubits

Curiosity and a passion for research is taking four U of T students to the final frontiers of health and space. A paper by the student research team, presented at a recent international conference of space experts, is the first step in a process that could inform future research into the dental woes of space travellers 

Sasha Weiditch

Sasha Weiditch is the fourth person in her family to graduate from U of T—her two sisters and mother are all alumnae—however she’s the first in the family to focus on science. Weiditch began her education at UTM as an undergraduate student in the BSc program.

Scott Prosser

Professor Scott Prosser, a specialist in molecular biophysics at the University of Toronto Mississauga, has been awarded the 2017 Royal Society of Chemistry Jeremy Knowles Award. The Jeremy Knowles Award is awarded to recognize and promote the importance of inter- and multidisciplinary research between chemistry and the life sciences.

Courses You Would Love

Green Tech

We discuss the species concept, quantification and cost-benefit analysis of biodiversity and extinction, causes, consequence, diagnosis and treatment of population declines.

Life Cycle

The course will focus on how genetic variation arises and is maintained, mechanisms of evolutionary change and how these mechanisms lead to adaptation, sexual selection, speciation and co-evolution.

Benzene Ring

The chemistry of selected classes of naturally occurring molecules such as those below, with emphasis on structure, stereochemistry, properties and synthesis.

Planning Ahead

Whether you want to land your dream job, conduct groundbreaking research, or start your own business, we can get you there. Here are resources to help you explore your career options.

Career Options

Created by our Career Centre, the Careers by Major database identifies some potential career fields, how to gain related skills and experience, and useful resources and job samples. But always remember, your program of study doesn't have to determine your career!

Program Plans

Program Plans are quick and accessible overviews of the many academic and co-curricular opportunities available to help you get the most out of your UTM experience.

Tip Sheets

The Career Centre offers dozens of tip sheets with helpful information about topics related to searching for work, planning your career, and pursuing further education.

View to the U: An eye on UTM research

View to the U is a podcast that features U of T Mississauga faculty members from a range of disciplines who will illuminate some of the inner-workings of the science labs and enlighten the social sciences and humanities hubs at UTM.

Peter Kotanen

On this latest episode of VIEW to the U, Professor Peter Kotanen from the Department of Biology at UofT Mississauga discusses his research and current projects, which have “ecological interactions between plants and their natural enemies,” such as herbivores, insects, and pathogens, at their core.

Other Programs to Consider



Biotechnology in modern society is the "application of scientific and technical advances in life science to develop commercial products”. This program combines biological sciences (genetics, biochemistry, molecular biology, microbiology, cell biology) with other science disciplines (chemistry, engineering, information technology, robotics, etc.).

Comparative Physiology

Comparative Physiology

Physiology is the study of living matter and its interaction between internal and external environments. It integrates physical and life sciences in order to understand body functions and the origins of disease in both plants and animals.
