For the states of the fission yeast cell cycle in Figure 3, we use the ordered gene set {Start, SK, Cdc2/Cdc13, Ste9, Rum1, Slp1, Cdc2/Cdc13*, Wee1/Mik1, Cdc25, PP}.
To test this, we induced a state of mitochondrial hyper-fission in rat fibroblasts by de-regulating Drp1, a dynamin-like GTPase that participates in the terminal fission process.
In many of these studies, the hyperfused state is induced by knockout of fission proteins, which creates a static hyperfused state.
Thus, it remains an open question whether the stability, maintenance, and transmission of the heterochromatic state in fission yeast occur through a mechanism that depends on the persistence of the nucleating sequence.
In equilibrium state the burning region contains a spectrum of fission products as well as higher actinides.
Our analyses provide insights into the mechanism that allows the propagation of the heterochromatin state in fission yeast, an organism that lacks DNA methylation.
The difference is that in dynamic hyperfused states, there can still be an appreciable rate of fission (e.g. if fusion proteins are overexpressed), whereas in static hyperfused states there are (almost) no fission events (e.g. if fission proteins are knocked out or heavily downregulated).
In the concerted mechanism, ANDN or SN2, the reaction proceeds through a trigonal bipyramidal pentacoordinated transition state, in which fission of the bond of the leaving ADP group and formation of a bond to the nucleophile's hydroxyl group (OH) both occur at the same time.

Similarly, Davidich et al.[22] found thirteen different steady states for the Boolean model of the cell cycle of fission yeast (Figure 3).
