CELL BIOLOGY

Bacterial ID Lab ('H')
Step into the shoes of a lab scientist and conduct virtual lab procedures. "The purpose of the lab is to familiarize you with the science and techniques used to identify different types of bacteria based on their DNA sequence....The techniques used in this lab are applicable in a wide variety of settings, including scientific research and forensic labs." By the Howard Hughes Medical Institute.
