分子遗传学系由医学大楼管理，有近100名教职员工，其实验室位于医学大楼内
The Department of Molecular Genetics is administered from the Medical Sciences Building and has nearly 100 faculty members whose labs are located within the Medical Science Building, the Best Institute, the Donnelly Centre for Cellular and Biomolecular Research, the FitzGerald Building, the Hospital for Sick Children, Mount Sinai Hospital, the Ontario Institute for Cancer Research, and Princess Margaret Hospital.<br>The Master of Science and Doctor of Philosophy programs in Molecular Genetics offer research training in a broad range of genetic systems from bacteria and viruses to humans. Research projects include DNA repair, recombination and segregation, transcription, RNA splicing and catalysis, regulation of gene expression, signal transduction, interactions of host cells with bacteria and viruses, developmental genetics of simple organisms (worms and fruit flies) as well as complex organisms (mice), molecular neurobiology, molecular immunology, cancer biology and virology, structural biology, and human genetics and gene therapy.<br>Computational biology seeks to help understand biological systems using computational methods to take advantage of large and complex data increasingly generated by genomics technologies. Systems Biology studies biological systems as a whole, considering properties not apparent when examining one component at a time, and requires a combination of experimental and computational methods to map and understand these complex systems. Computational and systems biology are often combined and share the goals of understanding how biological systems work at the cellular and molecular level, how these systems may break to cause disease and how to fix these failures and develop useful therapies.
