PSY397H1 Lecture Notes - Lecture 6: Cyanobacteria, Protein Set, Stromatolite
Document Summary
Lecture notes: the kai cycle - molecular clocks. Below is the clock that has been emphasized before --> structurally like all other clocks. Consists of a negative feedback loop that forms the core circuit (left) Then is stabilized by the positive size, which is still a feedback loop, but results in production of the clock-cycle dimer to regulate (right) This is a positive drive that drives the negative feedback loop. Wcc in neurospora is activated by light (below) Phase shift and subseq entrainment in any organism involves light interacting with the cycle to increase or decrease. Mammalian clock is shown below --> output is shown briefly in the graph. Set of clock genes that are rhythmically set. Below is a landscape of a cell --> genome is becoming more or less active in diff places. Shows the time of day at which things are being expressed, etc. Below is another representation of daily rhythms in a human.
