Chapter Nine Flashcards
For many years, stem cell research was considered quite controversial, especially the use of what?
embryonic stem cells and public funding
What reduced the need for human embryos?
breakthroughs in stem cell research
- Scientists have discovered a method in which an individual’s cells can be stimulated to act like stem cells. This reduces the need for donated stem cells
While research of any kind involving genet- ics will always be controversial, this topic is now covered in stem cell is titled what?
“Genetic Testing and Engineering.”
In 2003, the Human Genome Project succeeded in what?
mapping the human DNA sequence (Human Genome Project Information, 2011
DNA, or deoxyribonucleic acid, is what?
the small code contained in all human cells that determines our characteristics
Having a map of our personal DNA allows scientist to complete what?
genetic testing for a variety of purposes
Our legal system uses genetic testing to do what? (2)
- To match samples from crime scenes to criminal suspects
- Courts can use genetic testing to establish paternity and thereby ensure that financial support is provided to mothers and their children
In health care, genetic testing can be used for what?
help determine the possibility of developing certain dis- orders and diseases

Genetic testing has a variety of purposes in health care. Give an example and an issue of this
- If a patient has a family history of certain types of cancer, genetic testing might reveal a predisposition for that type of cancer, as well as the potential of passing it along to any biological chil dren.
- The problem with this type of testing is that it is new and not entirely reliable. Having the predisposition for cancer does not mean a patient will actually develop that cancer.
So, if a woman has a family history of breast cancer and genetic testing reveals a predisposition for that type of cancer, should she take preventive measures by having a mastectomy to remove her breasts?
This might seem extreme, but to some patients it might seem like a logical step. If individuals do decide to take such preventive treatments, should health insurance companies be required to pay for them, or should they be considered elective, requiring that patients pay for them out of pocket?
BRCA is an acronym for what? What does normal BRCA do, and what happens when it mutates?
BRCA is an acronym that stands for BReast CAncer susceptibility gene . Normally BRCA works to prevent the development of cancer cells . Those with BRCA mutations are not able to suppress the development of tumors, which can lead to breast or ovarian cancer .
What is Title II of the Genetic Information Nondiscrimination Act of 2008
- employers cannotuse genetic information to discriminate against employees or applicants applying for jobs.
- Genetic information includes the results of an individual’s genetic testing, as well as results of family members.
- It also extends to family history of genetic diseases.
- Employers are also prohibited from collecting genetic information or testing for certain genetic traits.
- Healthcare organizations are prohibited from sharing genetic information to any third party without patient consent.
The potential uses for genetic testing are currently _
Limitless
Genetic testing is used primarily for what?
to screen for certain diseases, which can provide patients with awareness and understanding
One ethical issue raised by genetic testing is what?
screening of children for certain traits—either before birth (in utero) or after birth
The Human Genome Project, as well as basic human rights, request what?
- We not reduce individuals to their genetic characteristics, but rather promote the respect of uniqueness and diversity
- This does not, however, prevent parents from wanting certain characteristics for their children (e.g., musical or physical ability) or attempting to prevent certain traits or diseases (e.g., diabetes or obesity)
The misuse of genetic information might seem like something out of a science fiction novel, but in our not-so-distant past, _ was practiced by certain societies
eugenics
What is known as an effort to improve the genetic makeup of a population
Eugentics
Who used Eugentics as a philosphy?
Nazi Germany used this philosophy to justify med- ical experimentation and even extermination of non-white and Jewish citizens.
How was Eugentics used in our country? What is an example?
- Certain nonconsenting adults were sterilized in an effort to reduce the risk of continuing the genetic line
- For example, certain states passed laws requiring the sterilization of patients classified as “mentally ill.” These laws were eventually overturned, but not before thousands of patients were sterilized.
What is cloning?
the copying of cells to create copies with similar genetic content
When is cloning considered acceptable?
for research purposes only (e.g., the cloning of Henrietta Lacks’s cells) and will not soon be used for any other purposes.
The Uniform Anatomical Gift Act, passed in 1968, allows what?
- anyone 18 years of age or older to donate body parts for the purpose of transplan tation after his or her death
- also allows next of kin to give permission regarding the donation of body parts.
- the law further addresses the donation of bodies for medical research or study
In addition to an advance directive, any living person can what?
can volunteer to donate organs.
To help simplify and organize the donation of organs, a second law what was passed?
National Organ Transplant Act) was passed in 1984. This act created a network for registering and matching organ donor recipients.
The Organ Procurement and Transplantation Network (OPTN) is what?
a private, nonprofit organization that contracts with the federal government
