Detailed explanation-1: -These core cell cycle regulators can cause key events, such as DNA replication or chromosome separation, to take place. They also make sure that cell cycle events take place in the right order and that one phase (such as G 1start subscript, 1, end subscript) triggers the onset of the next phase (such as S).
Detailed explanation-2: -The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins. Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK).
Detailed explanation-3: -Cell cycle regulators are commonly represented by cyclins, CDKs and CDK inhibitors, but can also include some of their substrates, interacting partners, and upstream regulators. These proteins have been well studied at molecular, cellular, and organismal levels in the context of cell proliferation control.
Detailed explanation-4: -The most important cell cycle regulators are the: Cyclin-Dependent Kinases (CDKs).
