17
Q

In Metaphase…

(Middle)

A

Spindle fibers connect to centromeres

Chromosomes line up in the center of cell

18

In Anaphase

(Attach/away)

Chromatids seperate to individual chromosomes

Moves to opposite ends

19
Q

In Telophase

(Twins)

A

Chromosomes condense and looks like chromatin

Nucleus re-forms

Spindle fibers breaks down
