What happens in metaphase
Spindle fibers move the chromosomes so they are lined up in the middle of the cell between the centrioles.
Define tumor

Define chromatids

What happens in anaphase

Meiosis only occurs in...
Reproductive organs.
Define Replication

What happens in telophase

Define gametes

Define mitosis
The division of chromosomes.
Define Centromere
The part where the two chromatids are held together.
What happens in cytokinesis
The cell organelle and starts to pinch in the middle.
Define causes
