I used Canva for this graphic. I enjoy using Canva for educational posters and presentations because it allows me to find template that fit very well with what I am trying to describe. I have used Canva to make many posters for OU iGEM, the OU American Society for Microbiology, and others. I can't count how many hours it has saved me by introducing a document format that I may never have come up with and fits my intent perfectly.
