CELL CYCLE Meaning and
Definition
-
The cell cycle refers to the ordered sequence of events that take place in a cell as it undergoes growth, division, and replication. It encompasses the various stages through which a cell progresses, from its formation to its division into two daughter cells. This highly regulated and intricate process ensures the accurate duplication and distribution of genetic material and organelles.
The cell cycle comprises two main phases: interphase and mitosis. Interphase is further divided into three stages: G1 (Gap 1), S (synthesis), and G2 (Gap 2). During G1, the cell grows in size, produces proteins, and carries out its specialized functions. The subsequent S phase is characterized by DNA replication, resulting in the formation of two identical sets of chromosomes. G2 phase marks the final preparation for cell division, during which the cell synthesizes more proteins and continues to grow.
Following interphase, the cell enters mitosis, where it undergoes nuclear division. Mitosis comprises several distinct stages: prophase, metaphase, anaphase, and telophase. These stages involve the condensation of duplicated chromosomes, alignment at the cell's equator, separation into two sets, and finally the formation of two new nuclei.
The cell cycle plays a pivotal role in growth, development, and repair of tissues in multicellular organisms, ensuring the maintenance of a consistent genome and cell number. Dysregulation of the cell cycle can result in various diseases, including cancer, underscoring the crucial role this process plays in maintaining cellular integrity.

Etymology of CELL CYCLE
The word "cell cycle" is formed from two components: "cell" and "cycle".
The term "cell" originates from the Latin word "cella", meaning a small room or chamber. In the context of biology, it refers to the fundamental unit of life, which comprises various structures and functions.
On the other hand, the term "cycle" has its roots in the Greek word "kyklos", meaning a circle or a round. It implies a recurring sequence or a series of events that happen in a repetitive manner.
When combined, "cell cycle" refers to the sequence of events that occur in a cell, leading to its growth, duplication of DNA, and division into two daughter cells. The term was first introduced in scientific literature in the mid-20th century as researchers began to understand the processes involved in cell division.
