What do we call the period of a cell's life where it will spend 90% of its entire life?
Interphase
100
Which phase of mitosis has chromosomes align along the plane in the middle of the cell?
Metaphase
100
DNA usually rest wrapped around a protein in the nucleus. What is the name of the protein that the DNA is wrapped around?
Histones
100
What do we call programmed cell death?
Apoptosis
100
When does cytokinesis occur in a cell's life?
Following telophase/mitosis.
200
In this stage of interphase, a cell will grow significantly and duplicate its organelles, proteins, and increase its cell membrane as it prepares for division.
G2 (in interphase)
200
During which phase of mitosis does a cell have its nucleus and nucleolus reappear? Chromosomes also disperse into chromatin during this phase.
Telophase
200
When DNA is wrapped around a protein, what do we called this complex?
Chromatin
200
Which form of tumor is a growth of cells that do not have the potential to relocate to a different part of the body?
Benign tumor
200
True or False: Cytokinesis is the division of the cell nucleus.
False. Cytokinesis is the division of the cytoplasm, cell membrane, and organelles. Mitosis is the division of the nucleus.
300
In this phase of interphase, the cell will duplicate its DNA so that it can give both daughter cells equal sets of DNA.
S phase (in interphase)
300
During which phase of mitosis do the chromosomes began to be pulled apart towards the poles of the cell, being pulled by the kinetochore mechanism back towards the centriole?
Anaphase
300
During mitosis, chromatin - a loosely coiled mass in the nucleus - condenses into another form. What do we call this form?
Chromosomes
300
List one cause of cancer.
1. unregulated cell division
2. cells avoiding apoptosis
300
How do the cells produced by mitosis compare to one another?
The two daughter cells are equal in every way - DNA, organelles, cytoplasm, etc.
400
Mitosis and cytokinesis are both in this phase of the cell cyle.
M phase
400
During which phase of mitosis does chromatin condense into chromosomes? During this phase centrioles begin migrating to poles of the cell and the nucleus begins to break down.
Prophase
400
What is the middle of a chromosome called?
Centromere
400
Name three treatments for cancer.
Chemotherapy
Radiation Therapy
Surgery
400
When an animal cell's membrane pinches inward during cytokinesis, this creates a ___________.
Cleavage furrow
500
What do we call an error in DNA replication?
a mutation
500
During which phase of mitosis do spindle fibers attach to centromeres, thereby creating kinetochores and begin the migration of chromosomes to the middle of the cell?
Prometaphase
500
What would we call "C" in this picture?
Sister Chromatids
500
Which form of tumor grows in a very rapid fashion? It has the ability to draw blood vessels towards it to feed its growth.
Malignant
500
In plant cells, a _______________ is built between the two daughter cells as they pull apart during cytokinesis.
Cell plate
