Document Summary
Midterm answer key will be posted sometime soon. The two times that are important is when the sun sets and the sun rises in general. Allows organisms to change their behaviour around dawn or dusk with accuracy. This accuracy is important because in natural selection, that determines the phase relationship and is what nature uses for selection. If this can"t be done on the molecular level, then phase angle of entrainment cannot be as easily adjusted. This was the first organism where we learned something about the post-translational oscillator. It can happen in a flask, or test tube as long as you have the right components. Kai proteins, phosphate, and atp --> all that"s required to get a basic oscillation. Provides organism with mechanism that works automatically, which can be then regulated and be made more precise --> the pto loop is shown below.
