How variable is protein production in single cells?

Event details

Individual bacterial cells can be very different from each other even when they come from the same ancestor. This is (partly) because the processes responsible for making protein from DNA are stochastic. I will attempt to derive expressions for the variance and mean of the number of proteins produced in a cell and show that the variability in protein production is much bigger than for a 'standard' Poisson process.
