The  copy must be accurate and copied exactly once. This is known as chromosome duplication. A structure called the centrosome also duplicates. The centrosomes help separate DNA during M phase.]]> 2021-02-16 21:00:54 UTC https://padlet.com/padmamynampaty/meyl26mlixutzvut/wish/1208753538 padmamynampaty https://padlet.com/padmamynampaty/meyl26mlixutzvut/wish/1208779855 All the enzymes needed to aid in the process of cell division have been produced. The cell has to grow some more and produce any molecules before it divides. G2 is the last chance for the cell to make more protein in preparation for division. The cell has twice the amount of DNA during G2 than it did during G1. G2 is necessary for the cell to make sure that all of the DNA is in intact.

The G2 to mitosis transition is the last checkpoint before the cell commits to entering mitosis. ]]> 2021-02-16 21:13:45 UTC https://padlet.com/padmamynampaty/meyl26mlixutzvut/wish/1208789078 1st checkpoint padmamynampaty https://padlet.com/padmamynampaty/meyl26mlixutzvut/wish/1208794985 Primary point that decides if the cell cycle continues or stops. External signals and growth factors can influence the cell cycle and affect the progress at or before this checkpoint.

Cytoskeleton disassembles as the spindle begins to form.Towards the end of prophase chromosomes attached by proteins in their centromeres called kinetic horse to microtubules from each pole moving the chromosomes toward the equator of the cell.

All chromosomes are aligned at the equator of the cell called the equatorial/metaphase plate. Sister chromitides are held at the centromere informing the presence of protein structures called kinetochore which holds the chromosomes and attaches them to the spindle.

Chromosomes are then pulled but to opposite poles. When the chromosomes separate into sets, one at each pole, anaphase is considered complete.

The splinder apparatus disassembles as the microtubules are broken down into tubulin monomers that can be used to form the cytoskeleton of the daughter cells. A cleavage furrow forms in the center of the cell. This indentation is made from constricting belt of actin filaments surrounding the inside of the cells circumference.

Cell plate grows outwards until it meets the existing wall resulting in two daughter cells.
