1. Epigenetics encompasses all processes that lead to heritable changes in gene expression (during
development or across generations) without changes in the DNA sequence itself. Study of
epigenetics include the following except: [refer to your handout on “Epigenome – Frequently
Asked Questions”]
a. the origin of RNA Correct
b. the study of how patterns of gene expression are passed from one cell to its
descendants
c. how gene expression changes during the differentiation of one cell type into another
d. the process through which environmental factors can change the way genes are
expressed.
2. Which of the following strategies is NOT part of the role of the genetic counselor:
a. Be supportive to the patient/family who have come for counseling.
b. Help the patient/family formulate their questions and concerns.
c. Tell the patient/families what decisions should be made as a result of their genetic
makeup.
d. Offer information and resources in a format that patients/families can understand.
3. A genetic marker is a known DNA sequence, a variation caused by a mutation or alteration in
the genomic loci that can be observed. In addition to identifying the chromosomal location of
mutant genes associated with hereditary diseases, genetic markers are currently used for all of the
following purposes except:
a.
b.
c.
d.
DNA typing for individual identification
Applying eugenic principles to improve the human gene pool Correct
DNA typing in tracking the spread of viral and bacterial epidemic diseases
Human population history studies through reconstruction of evolutionary history

Gene Therapy handout or Goggle)
a.
b.
c.
d.
Replacing a mutated gene that causes disease with a healthy copy of the gene
Inactivating, or “knocking out,” a mutated gene that is functioning improperly
Introducing a new gene into the body to help fight a disease
Designing the DNA to create new species which will be disease-free 5.
5. In 2017, a Chinese genetics researcher genetically altered the embryos of twin girls with CRISPR
technology. For what purpose was this genetic alteration performed. (Science. In Depth. Shock
greets claim of CRISPR-edited babies, 30 November 2018, Vol. 362, Issue 6419, p. 978.)
a. To change the gender of one of the embryos so that the parents would have a girl and
a boy.
b. To confer resistance to HIV infection.
c. To prevent muscular dystrophy.
d. To prevent microencephaly.
6. Identify 3 major goals of the Human Genome Project and comment on to what degree each goal
has been achieved. (Visit https://ghr.nlm.nih.gov/primer/hgp/goals to review goals of the Human
Genome Project.)
7. What is GWAS and what has it revealed about the genetic basis of schizophrenia? (Chapter 6,
textbook)
8. Identify 3 ethical dilemmas raised by the CRISPR genetic alteration of the twin girl embryos in
China.
9. Briefly describe the purpose and method of the Roscommon Family Study and identify 3 of its
major findings. (Textbook)
10. In order to protect Americans from discrimination against their genetic information, what are the
3 main areas addressed by the US Genetic Information and Non-Discrimination Act (GINA) of
2008?
