Prophase
First
What stage of mitosis is this phase?
Second
What phase of mitosis is this phase?
Third
What phase of mitosis is this phase?
Fourth.
Is this phase the longest of cell division?
Yes
What do the Centrioles and spindle fibers do during this phase?
The Centrioles separate and take up positions on opposite sides of the nucleus. Spindle fibers only start to form.
What do the chromosomes do during this phase?
The chromosomes line up across the center of the cell.
What happens to the sister chromatids in this phase?
The sister chromatids separate into individual chromosomes.
What happens to the chromosomes after they have separated?
Chromosomes gather at opposite ends of the cell and lose their distinct shape.
What are the three phases in interphase?
G1, S, and G2
What happens to the chromatin in the nucleus and what starts to break down?
The chromatin condenses into chromosomes and the nuclear envelope starts to break down.
What do the chromosomes do after getting separated?
They continue to move until they have separated into two groups.
What forms around the cluster of chromosomes?
A new nuclear envelope.
What does G1 phase do?
The cell increases in size and synthesizes new proteins and organelles.
What happens in the S phase?
Chromosomes are replicated and DNA synthesis takes place.
What happens during the G2 phase?
Organelles and molecules required for cell division are produced.
