Concept 9.1
What will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?
What is a cell with multiple nuclei, a cell with abnormal shape, etc.?
At which phase of mitosis do the attached sister chromatids become daughter chromosomes (or single chromosomes)?
What is anaphase?
Which is the first checkpoint in the cell cycle that will cause a cell to exit the cycle if this point is not passed?
What is G1?
Two sister chromatids attached by a centromere.
What is a duplicated chromosome?
Term used to describe cancer that can spread throughout the entire body through the bloodstream.
What is metastasis/malignant?
Explain the significant difference between prokaryotes and eukaryotes.
What is eukaryotes have a nucleus, prokaryotes do not.
If there are 20 centromeres in a cell at anaphase of mitosis, how many chromosomes are there in each daughter cell following cytokinesis?
What is 10?
Explain density-dependent inhibition.
What is as cells become more numerous, the cell surface proteins of adjacent cells bind to each other and send signals that inhibit cell division.
Another name for mitotic (mitosis) phase.
What is cell division?
List two specific cancer treatments, and tell how each treatment works.
What is radiation and chemotherapy?
A cell in G2 of the cell division cycle contains 20 chromatids. How many centromeres are present in this cell?
What is 20?
Movement of the chromosomes during anaphase would be most affected by a drug that prevents...
What is a spindle fiber?
The cell cycle is regulated at the molecular level by a set of proteins known as
What is cyclins?
Division of the cytoplasm.
What is cytokinesis?
The difference in cytokinesis between plants and animal cells.
What are cell plate vs cleavage furrow?
Somatic cells in elephants have 56 chromosomes. How many chromosomes would be carried by the gametes produced by elephants?
What is 28?
What is a cleavage furrow?
What is a groove in the plasma membrane between daughter nuclei?
Why do most cells in the human body divide infrequently or what happens to them when they are not needing to divide?
What is they are in the G0 phase?
Control point where signals regulate the cell cycle.
What is a checkpoint?
Explain the difference between ethics and bioethics.
Bioethics deals with life sciences and is a sub category of ethics.
Beginning with a fertilized egg (zygote), how many cells would be present in an embryo following a series of five cell divisions?
What is 32?
During which phase of mitosis in animal cells do centrioles begin to move apart?
What is prophase?
Explain anchorage dependence.
What is cells must be attached to another cell or extracellular matrix to divide?
Proteins released by other cells to stimulate cell division.
What is a growth factor?
Kinases drive the cell cycle, but they must be activated by attachment of a
What is a cyclin?
