Interphase
100
What happens at the end of mitosis when cytoplasm splits?
Cytokinesis
100
What is the purpose of Mitosis?
Mitosis produces 2 IDENTICAL daughter cells or to grow and repair
100

200
This phase is characterized by the condensing of chromatin into chromosomes and the dissolution of the nuclear membrane
Prophase
200
In what part of the cell does DNA replication occur?
the nucleus

300
This phase is characterized by the seperation of chromatids
Anaphase
300
What part of the cell cycle do cells spend most of their time?
Interphase!! (90%)
300
What happens after the chromosomes line up in the middle?
Spindle fibers separate chromosomes and pull them to either side of the cell
300
The protein that holds chromatids together
Centromere
400
Describe the structure of a DNA molecule.
Double helix.
400
This phase is characterized by the alignment of chromosomes at the center of the cell
Metaphase
400
During which phase of the cell cycle does DNA replication occur?
Interphase
400
What happens after the chromosomes separate?
They move to opposite ends of the cell in preperation of splitting
