Cycles of Cell Cycle
What are the 3 main stages of the cell cycle, in order?
Interphase, Mitosis, Cytokinesis
How many phases make up mitosis?
4
What phase of the cell cycle prepares the cell for division?
Interphase
List the phases of cell division in order.
Prophase, Metaphase, Anaphase, Telophase
The division of the cytoplasm of the cell during cell division is referred to as_____________.
Cytokinesis
What is cancer?
Uncontrollable Cell Growth
What is the longest phase in the cell cycle?
Interphase
True or False: Cytokinesis is included in the phases of mitosis.
False
In what phase is DNA replicated?
Synthesis
TRIPLE POINTS!!!
At which phase do the chromosomes become visible in the cell?
Prophase
What is the end result of cytokinesis?
Two identical daughter cells
What is something you can do to prevent cancer/minimize risk?
One of the following:
No smoking, breastfeeding, healthy diet, ideal weight, be active, limit alcohol, get vaccines, check for changes in body
The cell cycle results in two genetically _________ cells.
Identical daughter
True or False: Interphase is not included in the phases of mitosis.
True
Is the nuclear membrane still intact during interphase?
Yes
In which phase do the nuclear envelopes reform around the separated chromosomes?
Telophase
True or False: Cytokinesis is the division of the cell nucleus.
False. Cytokinesis is the division of the cytoplasm. Mitosis is the division of the nucleus.
What is the name of the proteins that regulate the timing of the cell cycle?
Cyclins
The cell cycle state where the cell grows to its full size, copies the DNA and organelles and prepares to divide is called the ________________.
Interphase
What type of reproduction is occurring during mitosis?
Asexual
What are chromosomes made of?
DNA and proteins (genetic material)
At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?
Anaphase
How many chromosomes should there be in each of the two new daughter cells?
Both should have the same amount as the parent cell
Apoptosis
What is the importance of the cell cycle to multicellular organisms with respect to tissue repair?
The cell cycle replaces damaged, worn, and aging cells
List the phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase
List the three parts of interphase in order.
G1, S, G2
Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.
Metaphase
If it takes one cell 24 hours to go through the cell cycle once, then how many cells will there be after 48 hours?
4
What is the difference between a benign and malignant tumor?
Benign - stays at the original site
Malignant - invasive, moves through body (cancer)
