Hello class, today we will be learning about mitosis!!
The interphase is the longest stage of the cell cycle. This is when the DNA in a cell in a cell is being replicated in order to prepare the cell to begin dividing!
The first stage is the prophase which is where the chromosomes condense and the nucleus and its membrane begin to disappear.
During the metaphase, the chromosomes are beginning to attach to spindle fibers and line up. This process leads into the anaphase which is when the chromosomes are forced apart by the spindle fibers and moved to opposite sides of the cell.
The next stage is the telophase. During the telophase, the nucleus is rebuilt in order for the chromosomes on each end of the cell to have separate DNA and a membrane. Which leads to the last and final stage Cytokinesis which is when everything is split up creating 2 identical cells that are an exact copy of the original.
If something in this cycle were to go wrong, the cell growth becomes abnormal and can cause other abnormalities, such as cancer. One of the checkpoints is the G1/S which prevents DNA damage and and regulates cell growth.
