The Cytoskeleton And Cell Division Flashcards
1
Q
What does the cytoskeleton do?
A
Give mechanical support and shape to cells
2
Q
What does the cytoskeleton consist of?
A
Different protein structures including microtubules which are found in all eukaryotic cells
3
Q
What are microtubules?
A
Hollow cylinders composed of the protein tubulin
4
Q
Where are microtubules found?
A
They radiate from the microtubule organising centre (MTOC) or centrosome
5
Q
What do microtubules do?
A
They control the movement of membrane-bound organelles and chromosomes
6
Q
What does cell division require?
A
The remodelling of the cytoskeleton
7
Q
What does the formation and brake down of microtubules involve?
A
Polymerisation and depolymerisation of tubulin
8
Q
What do microtubules form?
A
Spindle fibres that are active during cell division
