Centromere
|
|
|
___________ is the portion of the cell cycle in which the chromosomes are invisible under a light microscope because they are not yet condensed.

Condensation
|
|
|
__________ is the stage of mitosis characterized by the alignment of the chromosomes in a ring along the inner circumference of the cell.
