Cell Cycle - Definition, Phases, Examples, Regulation - Biology …
网页2017年5月30日 · The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason. New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Cell cycle | Description, Stages, & Checkpoints | Britannica
网页2024年9月16日 · The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
6.2 The Cell Cycle - Concepts of Biology - OpenStax
网页The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells.
Cell cycle - Wikipedia
网页The cell cycle, or cell-division cycle, is the sequential series of events that take place in a cell that causes it to divide into two daughter cells.
An Overview of the Cell Cycle - Molecular Biology of the Cell
网页The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.
Cell Cycle Phases and Checkpoints - Science Notes and Projects
网页2023年8月8日 · The cell cycle is a critical and complex series of events ensuring the proper growth and replication of cells. Its tight regulation ensures the maintenance of the genetic material across generations of cells. Disruption of this process can lead to diseases, the most notable being cancer.
Eukaryotes, Cell Cycle | Learn Science at Scitable - Nature
网页In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell...
