The cell cycle is one of the most fundamental processes of cell Biology. It prepares the cells to divide. It contains five phases and can be looked as a washing machine program. The phases are G0, G1, S, G2, M and will be described below
G0 Phase : This is a special resting state nothing really happens no cell growth just basic metabolic processes
G1 Phase: When cells enter this phase there is no going back the cell will divide and will have to complete the "program". During this stage cell grow take up nutrients to prepare for cell division. And checks if the environment is favorable. If not it will abort.
S Phase: Now the all DNA in the cell gets duplicated. S(synthesis) and you get chromosomes and sister chromosomes which are held together by special linkage molecules.
G2 phase: Another grow phase where the cell can prepare for last step taking up nutrients and growing. An before entering M phase environment and if all DNA is replicated is checked if not it will go in programmed cell death apopthosis.
M Phase: Actual cell division the M phase is complex and divided in another 6 steps: prophase prometaphase,metaphase, anaphase ,telophase and cytokinesis.
Prophase: Replicated chromsomes become more compact. The mitotic spindles start to assemble which have replicated and moved apart.
Prometaphase : breakdown of nuclear envelope chromosomes attach to mitotic spindle via specialised structures called kinetochores)
Metaphase: Chromosomes are alligned at the equator, halfway between spindle poles.
Anaphase: sister chromatides separate to form the 2 daughter chromosomes and each is puled to spindle poles
Telophase: chromosoms arrive at spindle pole. new nuclear envelope assembles. and contractile ring of actine fibers at equator begin to contract.
Cytokinesis Cytoplasm is divided in two by contractile ring. And two daughter cells are formed
A eukaryotic cell cycle typically consists of four stages: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). The cell alternates between these stages to grow and divide.
The cell cycle consists of five stages: G1 phase (cell growth), S phase (DNA synthesis), G2 phase (preparation for cell division), mitosis (nuclear division), and cytokinesis (cytoplasmic division), resulting in two daughter cells.
The G1, G2, and synthesis (S) stages make up interphase, which is the period in the cell cycle when the cell grows, carries out normal functions, and replicates its DNA in preparation for cell division. These stages are essential for ensuring accurate DNA replication and cell division.
he mitotic cell cycle is as follows:Gap 1SynthesisGap 2MitosisCytokinesisMitosis is the process by which the original cell (parent cell) divides to create an exact copy of the original cell (daughter cell). The mitotic cell cycle is composed of 5 stages that allow the cell to produce a "clone" of the original cell. The cell cycle proceeds as follows: Gap 1, Synthesis, Gap 2, Mitosis, and Cytokinesis. The first grouping of stages known as interphase, contains the first 3 of the 5 cell cycle stages.

what are the three stages of the cell cycle in a eukaryotic cell
it has four

The two stages of the cell cycle that is not a part of mitosis is interphase and death.

Well, There are six stages of cell
the cell cycles consists of 2 stages : mitosis and cytokinesis.
