Stem Cells
100
The longest part of the cell cycle when cells are performing normal functions is called this.
What is interphase?
100
This is the first phase of mitosis where chromosomes condense and the nuclear envelope disappears
What is prophase?
100
Another name for meiosis comes from the number of chromosomes that result in the daughter cells as compared to the number in the parent cell.
What is reduction division.
100
This is the name of the cell that is formed when a sperm penetrates an egg cell and their nuclei fuse.
What is a zygote.
100
This describes a stem cell and means that this cell is not yet a specific cell type.
What is an undifferentiated cell?
200
In this phase a cell will copy its DNA.
What is Synthesis or S Phase.
200
The daughter cells from mitosis are genetically _____ as compared to the parent cell.
What is identical?
200
This is the name scientists give to the daughter cells produced in meiosis. (not sperm or egg)
What are gametes?
200
This forms just after the sperm enters the egg cell and protects the cell from polyspermy.
What is the fertilization envelope or the fertilization membrane.
200
These stem cells are found in the early stages of development of an organism and can become any cell type.
What are embryonic stem cells?
300
Before the cell will enter mitosis, the cell performs these to look for errors.
What are checkpoints?
300
This occurs after telophase, when the cell divides the cytoplasm and other organelles.
What is cytokinesis.
300
This is the phase in which crossing over occurs.
What is prophase 1
300
A human zygote has ___ number of chromosomes.
What is 2n or 46.
300
An induced pluripotent stem cell can do this
What is become any cell type.
400
A cell that has errors in the cell cycle or ignores signals to stop dividing or to die may form this.
What is cancer?
400
In this phase, the spindle fibers retract, pulling the chromatids apart.
What is anaphase.
400
When two chromosomes that code for the same genetic information are paired, it is called this.
What is a homologous pair or tetrad.
400
This process occurs just after fertilization to create new cells.
What is mitosis?
400
Stem cells found in your body tissues are called this.
What are adult or somatic stem cells?
500
A cell may enter this resting phase where it is not dividing.
What is G0.
500
This cell type undergoes mitosis very quickly in an adult human.
What is skin, stomach lining, hair, etc.
500
This is a result of independent assortment in meiosis.
What is genetic variation.
500
As cells migrate to different areas of the developing organism and can only become specific cell types, this occurs
What is cell differentiation.
500
This is the injury suffered by Travis Roy which may someday be solved by stem cell research.
What is a spinal cord injury?
