Cell Cycle 1
Cell Cycle 2
Cell Cycle 3
Cell Cycle 4
Cell Cycle 5
100
What is the longest phase in the cell cycle?
Interphase
100
How many cells does cytokinesis end with?
Two identical daughter cells
100
What phase do chromosomes line up in the middle of the cell?
Metaphase
100
What is the first phase of mitosis?
Prophase
100
What stage is this cell?
Interphase
200
What happens to the nuclear membrane during prophase?
It dissolves, freeing the chromosomes
200
What is the significance of the centromere?
It is the point where sister chromatids are attached.
200
What happens to DNA during prophase?
It condenses and becomes visible
200
Which two cells represents anaphase?
7 and 9
200
What stage is this cell? 
Anaphase- sister chromatids pulled apart to opposite ends of the cell
300
Which letter represents mitosis of the cell cycle?
W
300
Define "chromatin"
uncoiled, loose DNA
300
What happens if a checkpoint fails?
Could potentially cause cancer, uncontrolled cell growth
300
When an animal cell begins to pinch in the middle during telophase, what is that area called?
Cleavage furrow
300
What happens to a cell if a checkpoint detects a flaw in the DNA?
Apoptosis- programmed cell death
400
What process MUST take place before mitosis can occur properly?
DNA replication
400
What is the role of the M checkpoint?
Checks that sister chromatids are correctly attached to spindle finers/microtubules
400
What forms in a plant cell during telophase?
Cell Plate (beginnings of a cell wall)
400
What is the purpose of the G1 checkpoint?
Evaluates the integrity of the DNA, checking for damage. Checks to see if cell has grown enough.
400
Which cell is at the latest stage of mitosis?
Y- two nuclei have formed, telophase
500
If a cell has 46 chromosomes in G1 (normal cell), how many chromosomes will it have after cytokinesis?
46, cell division ends with two identical daughter cells
500
Place these in correct sequence
A-Chromosomes line up in the middle of the cell
B- DNA condenses into chromosomes
C-Sister chromatids move to opposite sides of the cell
B, A, C
500
What phase does a cell enter after cytokinesis?
G1 of interphase
500
What structure plays a role in cell division but is only found in animal cells?
Centriole
500
During G1 phase a normal cell has 46 chromatids, how many chromatids will it have after S phase?
96- chromatids
