Q

mitotic spindle

A

chromosome movement

22
Q

Mictrotubules: higher-order structures

A

Axoneme (cilia, flagella)

23
Q

Axoneme (cilia, flagella)

A

9 doublets of microtubules, central pair, dynein arms, structural proteins

24
Q

Centrioles structure

A

(basal bodies)

  1. Hollow cylinders
  2. 160-230nm diameter
  3. 9 triplets of microtubules
25
Q

Centrioles movement

A

replicate during mitosis

migrate to the poles - organize the mitotic spindle

26
Q

MTOC

A

2 centrioles - all cell except neurons and RBCs

27
Q

Intermediate filaments

A

intermediate in thickness, NO polarity, NO motors

28

Q

Glucosaminoglycans Tissue and Cell Staining

A

Blue

44
Q

what particle does synthesis

A

ribosomes

45
Q

G-actin formation

A

globular so makes big globs

46
Q

what does plus and minus end mean

A

the plus end has faster polymerization than the minus end. It grows faster.

47
Q

how are the cylinders made in microtubules

A

alpha and beta tubulins polymerize head to tail to make cylinders that wrap in a cynlinder formation

48
Q

Dynein and Kinesins are both

A

ATPases

49
Q

Dynein v Kinesin

A

Dynein is bulkier

50
Q

purpose of motor proteins

A

move cargo/organelles

51
Q

what happens if you have a mutation in axoneme proteins

A

huge issues in motility

52
Q

what makes the beating of the cilium

A

dynein arms
