1.5 The Cytoskeleton And Micotubules In Cell Division Flashcards
1
Q
What is the cytoskeleton made up of
A
Different protein structures: filaments
CRUCIALLY : microtubules
2
Q
What is the function of the cytoskeleton
A
Offers mechanical support and shape to the cell
3
Q
What are microtubules made of
A
The protein tubulin
4
Q
What shape are microtubules
A
Hollow cylinders
5
Q
Where do microtubules radiate from
A
MTOC the microtubule organizing center, or centrosome
6
Q
What are the functions of microtubules
A
Control the movement of membrane bound organelles and chromosomes
Microtubules form the spindle fibers that are active during cell division
This means the cytoskeleton needs remodeling during cell division
7
Q
What does the formation and breakdown of microtubules involve
A
Polymerisation and depolymerisation of tubulin
