There are two phases in the cell cycle There are two phases in the cell cycle which splits between interphase and which splits between interphase and mitosismitosis
Interphase: G1 phase, S phase, G2 Interphase: G1 phase, S phase, G2 phase phase
Mitosis: Mitosis: Prophase, Metaphase, Prophase, Metaphase, Anaphase, Telophase Anaphase, Telophase
The cell cycle plays an important role The cell cycle plays an important role to our daily lives without out it we to our daily lives without out it we would not be alive, by making new would not be alive, by making new cells to replace our old ones helping cells to replace our old ones helping us to replenish our-cells us to replenish our-cells
The cell grows before the cloning The cell grows before the cloning of the DNAof the DNA
prepares to replicate DNAprepares to replicate DNA
At the end of this phase the cell At the end of this phase the cell
goes through the first check point goes through the first check point of the cell cycle that make sure if of the cell cycle that make sure if the cell is functioning normally the cell is functioning normally cells that cant divide stay at this cells that cant divide stay at this phase and cant move on phase and cant move on
DNA gets clone (chromosomes are DNA gets clone (chromosomes are being replicated)being replicated)
The DNA gets split at their The DNA gets split at their hydrogen bonds by helicase DNA hydrogen bonds by helicase DNA polymerase adds the corresponding polymerase adds the corresponding bases to the Strand of DNA forming bases to the Strand of DNA forming
two sister chromatids (identicaltwo sister chromatids (identical DNA DNA double helix molecules)double helix molecules)
During this process the centromere During this process the centromere starts to form which is the area that starts to form which is the area that is near the middle of the two is near the middle of the two chromosomes attaching them chromosomes attaching them together which gets split latertogether which gets split later
During this phase the cell cycle have During this phase the cell cycle have a check point where the DNA gets a check point where the DNA gets repaired if damaged repaired if damaged

Ensuring the whole of the DNA Ensuring the whole of the DNA and it’s components and it’s components
Including a third checkpoint Including a third checkpoint
Eukaryotic cell divides it-self by Eukaryotic cell divides it-self by separating the chromosomes in separating the chromosomes in the cell nucleus making two the cell nucleus making two identical cells and with nucleus identical cells and with nucleus
Prophase -Chromosomes Prophase -Chromosomes condense, the condense, the nuclear membrane breaks down, nuclear membrane breaks down, and spindle fibers formand spindle fibers form
Metaphase - The replicated Metaphase - The replicated chromosomes line up in the middle chromosomes line up in the middle of the cell of the cell
Anaphase -Chromosomes separate Anaphase -Chromosomes separate and the cell becomes elongated, and the cell becomes elongated, with distinct ends (poles)with distinct ends (poles)
Telophase-Nuclear envelopes re-Telophase-Nuclear envelopes re-form at the two poles and new cell form at the two poles and new cell membranes are formed to create membranes are formed to create two independent cellstwo independent cells
Cell wall forms and daughter cells Cell wall forms and daughter cells are bornare born
