The cell cycle is a vital biological process where cells grow and divide, forming new daughter cells. It's essential for organism development, tissue repair, and asexual reproduction in unicellular life. Eukaryotic cells undergo interphase and mitotic phases, while prokaryotic cells replicate via binary fission. The cycle is tightly regulated with checkpoints to prevent errors, ensuring genetic fidelity and proper cell function.

The cell cycle is the sequence of events that a cell undergoes as it grows and divides into two new cells
Role in growth, development, and tissue repair
The cell cycle is crucial for the growth, development, and tissue repair of multicellular organisms
Role in asexual reproduction
The cell cycle is equally important for the asexual reproduction of unicellular organisms
DNA replication
The cell cycle includes the replication of the cell's genome during DNA replication
Division of cytoplasm and organelles
The cell cycle culminates in the division of the cell's cytoplasm and organelles, creating two genetically identical daughter cells
Interphase is a period of cellular growth and preparation, divided into three stages: G1, S, and G2
Mitosis
Mitosis is the division of the nucleus during the M phase of the cell cycle
Cytokinesis
Cytokinesis is the division of the cytoplasm during the M phase of the cell cycle
Binary fission is the process of replication in prokaryotic cells
B period
The B period is the time between cell divisions in binary fission
C period
The C period is when DNA replication occurs in binary fission
D period
The D period encompasses the separation of replicated DNA and the division of the cell into two daughter cells
Regulation is vital to prevent the division of cells with genetic defects, which could lead to diseases such as cancer
Checkpoints are critical regulatory junctures within the cell cycle that monitor and verify the completion of processes before proceeding to the next phase
