网页2017年5月30日 · The two main parts of the cell cycle are mitosis and interphase. Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.” The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

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.
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.
2.4: The Cell Cycle and Changes in DNA Content
网页2023年6月20日 · Four stages of a typical cell cycle. The life cycle of eukaryotic cells can generally be divided into four stages and a typical cell cycle is shown in Figure \(\PageIndex{13}\). When a cell is produced through fertilization or cell division, there is usually a lag before it undergoes DNA synthesis (replication).
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, copies its DNA, prepares to divide, and divides. Learn more about the cell cycle and the proteins that regulate its progression.
6.2 The Cell Cycle - Concepts of Biology - OpenStax
网页The cell cycle has two major phases: interphase and the mitotic phase (Figure 6.3). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides. Watch this video about the cell cycle: https://openstax.org/l/biocellcyc.

网页2023年8月3日 · Three main cycles are involved in the cell cycle; chromosome cycle, cytoplasmic cycle, and centrosome cycle. The chromosome cycle involves DNA synthesis that alternates with mitosis. During this cycle, the double-helical DNA of the cell replicates to form two identical daughter DNA molecules.
Cell Cycle and Cell Division | Learn Science at Scitable - Nature
网页From this understanding, scientists then identified the four characteristic phases of the cell cycle: mitosis (M), gap 1 (G1), DNA synthesis (S), and gap 2 (G2).
Cell Cycle - National Human Genome Research Institute
网页4 天之前 · … 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.
