The Cytoskeleton And Cell Division Flashcards
1
Q
What is the cytoskeleton definition
A
Complex network of protein filaments that gives mechanical support and shape to cells found throughout the cytoplasm.
2
Q
What does the cytoskeleton consist of
A
Different protein structures including micro tubules
3
Q
What are mirotubles
A
Hollow cylinders composed of protein Tubulin. They radiate from the micro tubule organising center or centrosome.
4
Q
What do microtubules control
A
The movement of membrane-bound organelles and chromosomes
5
Q
What can mirotubules form and what does it mean
A
Spindle fibres that are active during cell division meaning the cytoskeleton needs remodelled during cell division.
6
Q
What doe the formation and breakdown of microtubules involve
A
Involves polymerisation and depolymerisation of tubulin
