What is a stem cell?

A
a cell from which a new cell that has a specialized function is formed
B
a mature egg cell that is capable of forming a new organism
C
a cell that has half the number of chromosomes of a parent cell
D
a specialized cell in the skin that identifies pathogenic organisms

The development of different cell technologies has led to changes in existing information. Which of the following is an example of a discovery that could cause such a change?

A
an experiment that confirms how water moves into and out of a cell
B
an experiment that shows a different way to measure a variable
C
an experiment that reproduces the results of a previous experiment
D
an experiment that reveals a new step in a metabolic pathway

One of the newest applications of cell technology is called cybrid embryos. This process involves replacing the nuclear material of an animal cell with human nuclear material. How might this process affect public policies about research by using stem cells?

A
The same policies and concerns about the use of human embryonic stem cells would most likely apply.
B
The embryos would most likely be treated like traditional animal embryos and regulated accordingly.
C
The process of forming cybrid embryos would most likely be banned by government regulators.
D
The embryos would be treated as regular cells because they are not fully human in origin.

Currently, most organs that are harvested for transplant are transported from the donor to the recipient packed in ice and must be implanted within a matter of hours. How is organ culture an improvement on this transport method?

A
Organs that are packed in ice can be damaged by frostbite during transit.
B
Cultured organs can be kept alive for several weeks before transplant.
C
Extra culture medium is easier and cheaper to transport than extra ice.
D
Organ cultures can be shipped as cargo rather than hand delivered.
7

Why is the ability to culture stem cells important?

A
Stem cells can be stimulated to develop into any cell type.
B
Stem cells are easier to culture than other types of cells.
C
Stem cells make reproductive cloning unnecessary.
D
Stem cells are easier to immortalize than cancer cells.
8

Why are immortal cell lines important for biological research?

A
They have two nuclei, allowing them to divide faster than normal cells.
B
They can replicate indefinitely and do not experience natural cell death.
C
They grow larger than normal cells so that they can divide into multiple cells.
D
They grow spontaneously rather than going through the process of mitosis.
9

How did the development of the HeLa cell line affect society?

A
It resulted in patient consent being required for tissues to be used in research.
B
It led to the production of the most widely studied mortal cell line in the world.
C
It prevented the collection of other human cell types for research.
D
It caused the contamination and destruction of other immortal cell lines.
10

Which therapeutic cloning application is most likely a benefit to society?

A
production of a new line of mouse cells for research
B
creation of a new flower variety for gardens in dry climates
C
generation of nerve tissue for treating paralyzed patients
D
formation of a new liver to be transplanted into a child
