What are the 3 main functions of microtubules in Eukaryotes? |
1. cellular reproduction 2. Structure 3. Intracellular/cellular movement
|
|
|
What are microtubules composed of? |
Dimers (pair of molecules) of alpha and beta tubulin (globular proteins) |
|
|
What do alpha and beta tubulin form? |
long, hollow, tubes, that are constantly built and destroyed |
|
|
Where do microtubules grow from?
|
Microtubule organizing centres (MTOC) |
|
|
How to the microtubules act as tracks? |
The motor protein kinesin "walks" on the microtubules, carrying transport vesicles throughout the cell |
|
|
How do microtubules work in mitotic cell division? |
Attach to chromosomes, forming the mitotic spindle that physically pulls chromosomes apart into their respective daughter cells |
|
|
What other structures do Microtubules form? |
