Dr. R. Thomas Broker Among model organisms, bacteria hold a unique place, as both models of infection and pathogenesis, and as research tools. More to the point, molecular biology was built upon the cell walls of lowly bacteria: The processes of DNA replication, RNA transcription, and protein translation, not to mention gene regulation, were all worked out in bacteria. Those early studies provided the foundations to understanding the more complex processes in eukaryotes. Despite their relati
