網頁Cell cycle progression is a highly regulated process orchestrated by numerous checks and balances to ensure that division and proliferation is a favored outcome. Progression is mediated by cyclin-dependent kinases (CDKs) and their partner cyclins.84,85 Each pair is associated with a certain phase of cell cycle. 網頁Sometimes, molecular or atomic basis. But anyway, this first phase of mitosis, the nuclear envelope, the nuclear membrane starts to disappear. The centrosomes migrate to the opposite ends of the cell. And our DNA condenses …
