Recommendations Papers that at least one of us has read and enjoyed, with a short summary and explanation of relevance. Important mathematical background that underlies transcriptional regulation, the most prevalent feedback system in biology. I find it interesting that biology separates (to some degree) the amount of protein expressed from a protein's function, and this separation allows for control over the number of proteins in the cell. -Kelsic [1] Modular functional modeling of feedback mechanisms in the heat shock response. An example of how protein numbers can be controlled via feedback vs. parameter tuning. [2] Experiment and modelling that demonstrate how negative transcriptional regulation can change the time-response of a genetic circuit.[3] Engineeging implementation of negative transcriptional feedback for control over the variance of protein distributions. An example of how transcriptional feedback can be used for precise gene control.[4] Theoretical paper discussing the minimum number of molecules required to perform stable switching. It's article #74 on his publications page -Milo A quorum sensing system regulates a gene that causes cell death. The result is a population control circuit. They're able to generate step-response-like plots of cell growth vs. time and show that with control the cells grow to a lower steady state value.
