-nuclear membrane breaks down
-phosphorylation of lamins by m-cdk
-chromosomes attach to spindle |

| -astral, kinetochore, interpolar |

Definition
-multilayered protein that binds to centromeres
-many MT (10-40) per kinetochore |
|
|
Term
|
Definition
-chromosomes line up in middle of spindle due to growth and shrinkage of MTs and motor proteins
-constant adjustment
-chromosomes held in place under alot of tension |
|

Term

Definition
-cohesin linkage broken
-triggered by activation of APC
-each chromatid pulled to pole |
|
|
Term
|
Definition
-A-shortening of kinetochore MTs
-B- sliding of centromeres |
|

Term
|
Definition
-nuclear envelope reassembles
-first cluster around chromosomes to form vesicles
-vesicles fuse to form nuclear envelope
-nuclear pores bring in nuclear proteins and chromosomes decondense
-then we need a lot of protein for transcription/translation |
|

Term
|
Definition
-begins during anaphase
-completed when nuclei are formed
-no MTs involved (actin and myosin)
-mitotic spindle dictates where the contractile ring is placed |
