7.345 Survival in Extreme Conditions: The Bacterial Stress Response (MIT)
Bacteria survive in almost all environments on Earth, including some considered extremely harsh. From the steaming hot springs of Yellowstone to the frozen tundra of the arctic to the barren deserts of Chile, microbes have been found thriving. Their tenacity to survive in such extreme and varied conditions allows them to play fundamental roles in global nutrient cycling. Microbes also cause a wide range of human diseases and can survive inhospitable conditions found in the human body. In this co

7.16 Experimental Molecular Biology: Biotechnology II (MIT)
The course applies molecular biology and reverse genetics approaches to the study of apoptosis, or programmed cell death (PCD), in Drosophila cells. RNA interference (RNAi), or double stranded RNA-mediated gene silencing, will be used to inhibit expression of candidate apoptosis-related genes in cultured Drosophila cells. Teams of 2 or 3 students will design and carry out experiments to address questions about the genes involved in the regulation and execution of PCD in this system. Some project
