During what phases in the cell cycle would you expect there to be large changes in the polymerization or depolymerization of microtubules? why are these changes necessary?

The polymerization or depolymerization of microtubules usually takes place on the M-phase of the cell cycle. Also known as the mitotic phase, it is a process in the cell cycle wherein the mother cell would be divided into two identical daughter cells using mitosis and cytokinesis.

The largest change in polymerization and depolymerisation of microtubule occurs in the M-phase.

Further Explanation:

Cell cycle refers to the sequence of event that takes place whenever the cell is going to divide. These events have to be highly regulated so that the daughter cells formed should have proper cell constituents in the cell.

The cell cycle has the following phases:

1. Interphase- Gap 1, Synthesis phase, Gap 2 phase.

2. M-phase- Mitosis/ Meiosis phase

During the interphase the cell prepares itself for the division to occur. There are also certain checkpoints present in this phase that restricts the cell to proceed further for the next phase until and unless the previous phase has not completed properly.

M-phase is the phase where the chromosomal separation occurs and which is distributed to the daughter cells.Mitosis occurs in the somatic cells while meiosis occurs in the germ cell.

M-phase has different sub stages. They are:

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase

For the distribution of the chromosomes to the daughter cells properly, the cell requires the help of microtubules, a cytoskeleton that moves these chromosomes by attaching to them and then moving it through polymerization and depolymerisation.

In the end the cytokinesis occurs and the parent cell divides and give rise to the daughter cell.
