Meiosis
What is the end result of Meiosis?
4 Haploid Daughter Cells
What is the first phase of the cell cycle and what happens?
G1, growing phase, proteins are produced.
Name the phases of mitosis in order
Prophase, metaphase, anaphase, telophase
What is cytokinesis?
When the cytoplasm divides
What is the major difference between meiosis and mitosis?
After the first set of chromosome division(meiosis 1) the cell does not enter the cell cycle and goes into meiosis 2
What happens during the S phase?
Synthesis DNA replication
What is the structure that organizes the spindle fibers?
Centrioles
Enters the G0 phase
Where does crossing over occur in Meiosis?
Prophase 1
What happens during the G2 phase?
DNA replication is complete and makes sure that it was done correctly.
One of two identical "sister" parts of a replicated chromosome
Chromatid
Uncontrolled cell division is?
Cancer
At what point in Meiosis are gametes formed?
After the end of meiosis 2, when each haploid daughter cell with 1/2 a set of normal chromosomes has had time to mature
What happens during the M phase?
Mitosis cell divides
The term for when the cytoplasm in a cell splits to form two new cells is what?
Cytokinesis
What must be copied correctly for the cell to pass the G2 checkpoint?
DNA
When will a zygote be formed?
When 2 haploid gametes combine to form a complete set of chromosomes
Where are the checkpoints found within the cell cycle?
G1 and G2 phases
Sister chromatids are joined at an area called the
Centromere
What is the underlying cause of cancer?
