Popular lecture: Your body is made up of a variety of kinds of cells: heart, skin, etc, and all the information the cells require to become these different kinds of cells is stored in their DNA as genes. You might imagine that different cell types contain different genes, however this is not the case! All cells contain the same genes, and different cell types are made by simply making use of different genes. That is, cells need to make decisions about which genes are expressed and which ones are not based upon what kinds of cells they are and what their environment is. Cells use molecular machines to sense their environment and, based upon that information, make decisions about which genes to express in order to adapt, survive, and become the type of cell they need to be. I will describe the insights and tools physics gives us to study how these machines work and are able to get around inside the cell to do their job.
