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 - Wikipedia
In eukaryotic cells (having a cell nucleus) including animal, plant, fungal, and protist cells, the cell cycle is divided into two main stages: interphase, and the M phase that includes mitosis and cytokinesis. [1] During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles.
Cell cycle | Description, Stages, & Checkpoints | Britannica
2024年10月30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.
Cell Cycle Phases and Checkpoints - Science Notes and Projects
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.

2023年2月2日 · A eukaryotic cell cycle consists of two main parts: 1) interphase and 2) mitotic (M) phase, and an alternative part called the G0-phase. 1) Interphase. It is the first phase of the cell cycle, recognized by the growth period where the chromosome gets duplicated as the cell prepares for division.

2023年8月3日 · The cell cycle is the sequence of events occurring in an ordered fashion which results in cell growth and cell division. The cycle begins at the end of each nuclear division and ends with the beginning of the next. A cell cycle acts as a unit of biological time that defines the life history of the cell.
Cell Cycle – Definition, Phases, Checkpoints, Regulation
2024年10月23日 · The cell cycle comprises a series of phases that govern the growth, replication, and division of cells. This cycle is crucial for cellular reproduction, development, and tissue maintenance across various organisms. A typical eukaryotic cell cycle includes two main phases: interphase and the mitotic (M) phase.
An Overview of the Cell Cycle - Molecular Biology of the Cell
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.

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...

1 天前 · Cell cycle is the name we give the process through which cells replicate and make two new cells. Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.
