Term
| Three parts of the Cytoskeleton |
|
Definition
| Actin, Microtubules, Intermediate Filaments |
|
|
Term
|
Definition
| Found in nuclear lamina, ropelike fibers, forms meshwork to give frame |
|
|
Term
|
Definition
| Made of actin subunits, flexible, concentrated around cortex, |
|
|
Term
|
Definition
| Long and hollow, attached to centromere during mitosis/meiosis, most rigid, tubulin polymers |
|
|
Term
| Which forms a network in cytoplasm? |

Term
| Which support nuclear envelope? |
|
Definition
|
|
Term
| How many protofilaments in tubulin? |
|
Definition
|
|
Term
| GTP controls growth of microtubules. How? |
|
Definition
| Tubulin dimers BIND GTP and CLEAVE into GDP and Pi. As long as the BINDING to the + site is faster than the CLEAVING, the microtubule will grow. |

Term
|
Definition
| liquid vs aqueous environment |
|
|
Term
|
Definition
| Moves around due to dynein |
|
|
Term
|
Definition
| thin flexible strands, polar and non polar end, dynamic (continuously growing and shrinking) |
|
|
Term
| ATP hydrolysis _____ the stability of actin. |

Definition
|
|
Term
| Polymerization of G-Actin |
|
Definition
| Nucleation (g-actin forms stable monomers), elongation (rapid addition of monomers), steady state (no additional monomers, but ends still dynamic) |
|
|
Term
|
Definition
| binds to g-actin (not f-actin) and is thought to be a G-ACTIN REGULATOR or else all actin would be filamous. gross. |
|
|
Term
|
Definition
| nucleotide exchange factor, allows GDP to swap for GTP and regeneration of actin monomer |
