Today, Dr. John McCutcheon of Arizona State University joins the #QualityQuorum to discuss the work he and his research group do to investigate the strategies by which microbes become symbionts of other cells. After all, the mitochondria and chloroplasts of eukaryotic cells, including yours, were once bacteria!
