Cell Cycle
... The cell cycle is a series of events that lead to cell division and replication, consisting of four phases: G1, S, G2 and M. The activation of each phase depends on the proper completion of the previous one. The cell cycle commences with the G1 phase, during which the cell increases its size. During ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
