Flashcards in Microtubule section 2 Deck (11):
When do centrioles divide?
During S phase. has to be before mitosis
How does duplication of centrioles occur?
During S phase mother and daughter separate, then both become mother's then they replicate themselves, and then during m phase they will divide and be housed in their own pericentrioler space
Many cells have at least 1
shorter, non motile
sensory function. Alternate between being basal bodies and centrosomes
SAS-6 dimers naturally associate to form a ring (in sets of 9)
This could be a template for formation of the centriole.
build up of a crystal/a protein structure
Is the central strand of a flagella has a 9x2+2
What two types of forms of attachment are seen with motor proteins and microtubules.
They will either anchor to a vesicle and move it along a microtubule or they will anchor themselves to a large organelle and move the microtubule
What does the following do
Motor head: binds to the microbule "walks"
motor tail: binds to a membrane structure like a vesicle
kinesins: Walk towards the positive ends
Dyneins: walk towards the negative ends
axonemes have which motor protein within them. How is it modified?
Dyneins: they have three heads instead of just two
Ciliary dyneins are also known as?
