PDF Lecture 7 Biology Diagrams The Cell Cycle. Mitosis is part of a precisely controlled process known as the cell cycle. The cell cycle is the regulated sequence of events that occurs between one cell division and the next. The cell cycle has three phases: interphase. nuclear division (mitosis) cell division (cytokinesis) The length of the cell cycle is very variable depending on environmental conditions, the cell type and The period required to complete one cell cycle (from beginning of one cell division to the beginning of next) is called generation time. It is 24 hours in human cells and 90 minutes in yeast. Cell cycle is simpler in prokaryotes and more complex in eukaryotes.
The cell cycle is the highly regulated sequence of events that occurs between one cell division and the next The cell cycle has three phases: interphase : during interphase the cell grows and carries out its normal cellular functions, e.g. synthesizing proteins and replicating DNA ready for mitosis During interphase, the cell spends most of its time performing the functions that make it unique. Mitosis is the phase of the cell cycle during which the cell divides into two daughter cells. Interphase. The interphase stage of the cell cycle includes three distinctive parts: the G 1 phase, the S phase, and the G 2 phase. The G 1 phase follows Cell cycle checkpoints 1. G1 Checkpoint. The G1 checkpoint is the first checkpoint in the cell cycle of a mammalian cell and the start point in the yeast cell that determines whether the cell enters the cell cycle or not. The checkpoint is present between the G1 phase and S phase and is responsible for the entry of the cell in the division phase.

Following interphase, the cell enters the M phase, which consists of mitosis and cytokinesis.Mitosis is the process where replicated chromosomes are evenly distributed into two new nuclei, while cytokinesis involves the physical separation of the cytoplasm and organelles, culminating in the formation of two distinct daughter cells. This orderly progression through the cell cycle is
