Cell Cycle Regulation

Cell Cycle Regulation (pronunciation: /sɛl saɪkəl ˌrɛɡjʊˈleɪʃən/) is a crucial process in the life of a cell. The term originates from the Latin words 'cella' meaning a small room and 'cyclus' meaning circle, combined with the Latin 'regula' meaning rule.

Overview

The cell cycle is a series of events that take place in a cell leading to its division and duplication. Regulation of this cycle involves several key proteins that control the progression of a cell through the cycle and ensure that the cell is ready to divide.

Phases of the Cell Cycle

The cell cycle is divided into four main phases:

  • G1 Phase: The cell grows in size and prepares for DNA replication.
  • S Phase: DNA replication occurs.
  • G2 Phase: The cell prepares for division.
  • M Phase: The cell divides into two daughter cells.

Regulation

Regulation of the cell cycle is achieved through a complex series of proteins and enzymes that monitor and control the progress of the cell through the cycle. These include cyclins, cyclin-dependent kinases (CDKs), and tumor suppressors.
