Interphase and Mitosis
Most cells grow, perform activities, and divide to make new cells. Eukaryotic cells divide to create new cells through the processes of mitosis or
meiosis. The series of steps that a cell undergoes in its growth and development is called the cell cycle. The two main phases in the cell cycle
are interphase and mitosis. Mitosis is the process where a parent cell with copied DNA separates and results in daughter cells that are identical
to the parent cell. The cell spends most of its time in interphase as it passes through the cycle. Checkpoints and regulator molecules control
the cell cycle.
Regulator molecules either promote a cell through the cycle or halt the cycle. Positive regulation molecules are proteins that move a cell through
the cycle when it meets the correct requirements. If the cell does not meet the requirements, negative regulation molecules will either try to
repair the damage or signal for apoptosis.
In order for a cell to move through the cycle, it must go through several checkpoints. The G₁ checkpoint makes sure that the cell has favorable
conditions for division. The cell must have enough growth and energy reserves to proceed onto the next phase of the cycle. At this stage, DNA
is also inspected for damage. DNA that is not suitable, or can not be repaired, will not move through to the S phase to be replicated and will exit
the cell cycle by entering the inactive Go phase. The cell encounters the next review at the end of the G₂ phase. The G₂ phase includes protein
synthesis and another round of growth. The G₂ checkpoint assesses the size and protein reserves of the cell as well as the accuracy of the
chromosome replication. If DNA is damaged, the cell tries to repair the damage before the beginning of mitotic division. The M checkpoint
determines if all of the sister chromatids are properly attached to spindle microtubules and ready for separation.
The model shows the checkpoints of the cell cycle.
