Gene expression is the process by which information coded in a cell’s DNA is converted into functional products—most often the proteins needed for all aspects of life. Among other topics, scientists who study gene expression are interested in how the process is regulated by cells, what happens when gene expression goes wrong, and how gene expression can be hijacked by disease-causing bacteria and viruses. WPI experts on gene expression can speak on gene expression’s role in cell division in tumors and in infectious diseases like tuberculosis, how changes in gene expression help some bacteria survive stressful conditions, and gene expression in synthetic biology.
