“12th Class Biology Chapter 21 Quiz: Cell Cycle” The cell cycle is the fundamental process by which cells grow, divide, and replicate. A cell cycle is a series of events a cell undergoes to duplicate its contents and divide into two daughter cells. Understanding the cell cycle is important in understanding how organisms grow, repair tissue, and maintain homeostasis. This chapter deals with the cell cycle phases, including the critical processes of mitosis and meiosis involved in cell division. Strengthen your understanding with our MDCAT Quiz and free flashcards designed to aid in reinforcing knowledge and excelling in exams.
The Regulation of the Cell Cycle
Progression through the cell cycle is controlled by a series of checkpoints and regulatory proteins, which are referred to as cyclins and cyclin-dependent kinases—CDKs. Such proteins make sure that the cell cycle goes forward only when specific conditions are met, like DNA replication being complete or the chromosomes properly aligned before division.
Checkpoints in the G1, G2, and M phases serve as critical control points that prevent the cell from dividing prematurely or inappropriately. If errors are detected, such as damaged DNA, the cell cycle may be halted to allow for repair, or in cases of irreparable damage, the cell may undergo apoptosis (programmed cell death).
