Web1 day ago · As known, the cdc25-22 cell does not initiate the mitotic phase at the restrictive 35â—¦C. Thus, to quantify the septum position in cdc25-22 cells, we incubated the cells at 35â—¦C for 3 hours and then quenched the temperature to 25â—¦C. Most of the cells undergo mitosis immediately and form a septum after 40 − 50 mins.
