New ways of creating molecules in the lab are energizing the collaboration between chemistry and biology. Dr. Stuart Schreiber examines how technological advances in chemical synthesis and information science, coupled with data from genome projects, have made possible a research approach called chemical genetics. See how Dr. Schreiber uses chemical genetics to create small molecules that probe the functions of cellular proteins to change the way they work. These new molecules can be used to better understand how proteins work, and in some cases may become candidates for new medicines. From the Series:HHMI’s Understanding Biomedical Research Series
