Chromosomes
Mitosis
100
One half of a duplicated chromosome
What is a sister chromatid?
100
The spindle fibers attach to the centrosomes of each chromosome in this phase.
What is metaphase?
200
This holds two chromatids together?
What is a centromere?
200
The centrosomes split, and sister chromatids go to opposite ends of the cell during this phase.
What is anaphase?
300
The nuclear envelope (or membrane) breaks down in this phase.
What is prophase?
400
Before this genetic material condenses, the chromosomes are not visible.
What is chromatin?
400
The phase in which two nuclear membranes are formed.
What is telophase?
500
The ________________ move to opposite ends of the cell pulling the spindle fibers.
What are centrioles?
