1v- The cytoskeleton and cell division Flashcards
1
Q
What does the cytoskeleton do?
A
Gives 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 cyclinders composed of the protein tubulin
4
Q
Where do microtubules radiate from?
A
The microtubule organising centre (MTOC) or centrosome
5
Q
What do microtubules do?
A
Control the movement of membrane-bound organelles and chromosomes
6
Q
What does cell division require?
A
Remodelling of the cytoskeleton
7
Q
What does the formation and breakdown of microtubules involve?
A
Polymerisation and depolymerisation of tubulin
8
Q
What do microtubules form?
A
The spindle fibres that are active during cell division
