Prometaphase Flashcards
1
Q
list steps of prometaphase
A
nuclear envelope disappears
nucleolus disappears
kinetochores develope
centrosomes move apart and spindle fibers appear
2
Q
what happens when centrosomes move apart and the spindle fibers appear?
A
spindle fibers bind to the kindetochores
chromosomes move towards the equator
3
Q
kinetochore microtubles are attached to what
A
to chromosomal kinetochores
4
Q
what do polar microtubules do?
A
interact with spindle MT’s from the opposite poles
5
Q
what are abstral microtubules
A
form the asters at each pole
dense starburst of microtubules that interact with plasma membrane
