                    The research and development phase of synthetic biology is an expensive and time intensive phase. When we

                    parts interact with one another and their behaviors. While not every experiment in the lab goes perfectly,
+
−
                    modelling effectively will limit the rate of failure when we test our theories. For example, modelling a

                    protein in PyMOL may provide insight into what residues are exposed on the surface for a mutagenesis.

Purpose

The QGEM 2020 team would like to acknowledge and thank all of our team and friends for making this year’s project as great as it could be! Although the lab was closed because of the COVID-19 pandemic, our team stepped up remotely, and we could not thank them enough! While our institution does not teach an iGEM or specific synthetic biology course, much of our team is supported by and takes courses through the Department of Biomedical and Molecular Sciences and Department of Chemical Engineering. Many members of our wiki team attend the School of Computing at Queen’s University. QGEM each year begins the hiring process for a new director in early winter, shortly after the previous team attends the iGEM final jamboree. Leads are hired in late February, with a call for volunteers shortly after that. Brainstorming on this year’s 2020 project began in March, with the first models and work started in late April of 2020 after winter semester exams.
