Cell Cycle 1
What are the two phases of the cell cycle?
Interphase and M Phase (mitotic phase)
Name the phases of interphase in order.
G1, S, G2
In what phase of mitosis do the chromosomes line up?
Metaphase
What is another name for the M checkpoint?
Spindle Checkpoint
What are the three reasons cells divide?
Growth, Repair & Replacement, Reproduction
What phase in the cell cycle is the shortest?
M Pase
When during the cell cycle do you call the genetic material chromatin?
Interphase
Name the phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase
How is metaphase and anaphase different?
Metaphase - chromosomes lined up. Spindle fibers attached at the centromere.
Anaphase - sister chromatids are separated and being pulled in opposite directions by spindle fibers and centrioles.
When does the nuclear envelope reform?
Telophase
What phase of the cell cycle does cytokenisis take place?
The M Phase (mitotic phase)
What phase of interphase is there the most cell growth?
G1
that deteriorates the same time the nuclear envelop deteriorates?
Nucleolus
When do the spindle fibers first start forming?
Prophase
Instead of a cleavage furrow, plant cells form what?
Cell Plate
True or False - The cell cycle takes 48 hours
False - it is 24 hours
The cell performs basic preparation for division during what phase of the cell cycle?
G2
When do the chromosomes first become visible?
Prophase
What sentence can help you remember the phases of mitosis?
Please Make Another Taco
What is two chromatids connected by a centriole?
Chromosome
When during the cell cycle does DNA replicate?
S Phase
What checkpoint includes checking environmental conditions, cell growth and making a decision to move forward with the cycle?
G1 Checkpoint
What pulls the siter chromatids apart?
Spindle Fibers
A parent cell that has 10 chromosomes lined up during metaphase will have two daughter cells with how many chromosomes each?
5
