- Do you guys know the 1st phase of a cell cycle?
- Yes it is the Interphase
- First, the cells grow in size, then replicate the DNA, and then prepare for cell division.
- In this phase, chromosomes condense and coil. The nucleolus disappears, and the nuclear envelope breaks down.
- So the next one has to be Telophase?
- But what's afterInterphasethen?
- Next is the beginning of Mitosis. This is called the Prophase .
- The next phase is the Metaphase which means the middle stage.
- In this phase, the spindle fiber attaches to protein and aligns the chromosomes along the equator
- So what's next?
- Who knows what comes after Prophase?
- So the next stage is anaphase, right?
- Yes, and that's when chromatids turn into chromosomes.
- Yes, and those chromosomes are pulled towards opposite poles of the cell.
- Yes, and that's also when the nuclearenvelope reforms, and spindle fibers break apart.
- Yes, that's when a set of identical chromosomes is placed at each pole of the cell.
- And an easy way to remember the 4 parts of mitosis is PMAT !
- Next is called the Cytokinesis which completes the cell cycle.
- Yes, in this phase,thecytoplasm divides into 2 identical daughter cells.
