πŸ”¬ Mitosis (CCEA)

The cytoskeleton

Cell division requires the active remodelling of the cell’s cytoskeleton. The cytoskeleton is made of multiple kinds of protein that offer it the right structure and aid during the process of division.

 

The centriole is a tubey spaghetti thing that aids in cell division when the duplicated chromosomes need to move into their subsequent new offspring cells from the parent cell (during mitosis).

 

 

They’re made of a special protein called tubulin because they’re tubeeeeeeeeeeeees. Why didn’t they call it spaghettulin? I guess spaghetti aren’t hollow but…

 

Microtubules also play a key part in how cell organelles are moved and placed within the cell. Two associated centrioles form the centrosome. The microtubules are also where spindle fibres extend from when they separate chromosomes during cell division.

 

Stages of Mitosis

Prophase, metaphase, anaphase, telophase and cytokinesis.

 

 

There’s no easy way around these stages, so just bloody learn them. Actually there is an easy way…
