Stem Cell Differentiation Stem-Cell Niches Dolly the Sheep Uses of Stem Cells BIOL101 Exam Questions
100
What is undifferentiated?
This term describes how stem cells are "unspecialized."
100
What is differentiating?
Stem-Cell niches prevent stem cells from doing this.
100
What is an adult cell (differentiated cell)?
Dolly the sheep was the first mammal to be cloned using this type of cell.
100
What is regenerative?
Stem cells have this kind of property that makes it useful in growing tissues and organs.
100
What is sister chromatids?
These biological structures contain identical genetic information prior to crossing over.
200
What is mitosis?
This process allows stem cells to create new cells either identical to themselves or more specialized.
200
What is asymmetrically?
When connected to a niche cell, stem cells undergo mitosis in this fashion.
200
What is 276?
It took this many tries to successfully create Dolly the sheep.
200
What is a beating heart?
This organ was successfully grown using donor cells in 2016.
200
What is chromosome?
Every somatic cell has an identical set of this molecule,
300
What is totipotent stem cells?
This type of stem cell has the potential to differentiate into any type of cell.
300
What is a complex?
This area is where stem cells receive signals from the niche tissue.
300
What is G0?
The "resting" phase of a cell is referred to using this term.
300
What is white blood cells?
Leukemia is cancer of this part of the body.
300
What is 1/2?
In metaphase II, this ratio of DNA is present in reference to the amount of DNA present in the parent cell in G2.
400
What is red blood cells and white blood cells?
These are the types of cells blood stem cells can differentiate into.
400
What is cell-to-cell and cell-matrix interactions?
Stem cells receive differentiation signals through these methods (hint: not complex).
400
What is a cell from a mammary gland and an egg?
The embryo of Dolly was created using these two types of cells.
400
What is bone marrow?
This type of stem cell is donated to treat Leukemia.
400
What is inhibitive?
A relay protein in this pathway would lead to too much cell division.
500
What is nerve/brain cell?
A stem cell can differentiate into this kind of cell as part of the body's self-repair process when a person suffers from a stroke.
500
What is the cadherin complex?
Self-renewal factors come from this complex.
500
What is enucleation?
This is the process in which a nucleus is removed from a cell?
500
What is burns/stroke/muscle degeneration?
The use of stem cells to treat these injuries/sicknesses is being researched (list 2).
500
What is meiosis II?
If half of the gametes formed during meiosis are haploid and half have an abnormal number of chromosomes, then non-disjunction would have occurred in this phase of meiosis.
