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.

网页5 天之前 · cell cycle, the ordered sequence of events that occur in a cell in preparation for cell division. 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).
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.
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.

网页2021年12月23日 · 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.
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 actually...
Cell Cycle - National Human Genome Research Institute
网页3 天之前 · A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Cell Cycle Phases and Checkpoints - Science Notes and Projects
网页2023年8月8日 · The cell cycle is a series of events that cells go through to grow, replicate their DNA, and divide. This process is vital for the growth, development, repair, and maintenance of living organisms. A consistent and regulated progression through the cell cycle ensures the proper duplication and distribution of a cell’s genetic material.
