What phase do cells enter after mitosis is complete?
Centromere divide and chromosomes migrate towards the ends of the
cell.
Chromatin condenses to form chromosomes.
What is each chromosome called in a chromosome pair connected by a
centromere?
Master Yoda

What are the two parts of cell division?
This is the longest stage of cell cycle.
What structures form in prophase along which the chromosomes
move?
In which phase of mitosis is the last phase where chromosomes pairs
are together?
Which phase of the cell cycle is characterized by a non-dividing cell?
What structure is produced when protein fibers radiate from
centrioles?
What forms across the center of a plant cell during cytokinesis?
The period of cell growth and development between mitotic division.
If a cell lived for 24 hrs., this stage would represent 1 hr. of the
cell’s life.
