2.1 Medical Interventions

Genetic testing is used to determine all of the following except

• if someone has developed a genetic disorder

• if someone is a carrier of a genetic disorder

• if someone has an infection

• if someone will develop a genetic disorder

What was one purpose of the Human Genome Project?

• to break hydrogen bonds and separate DNA

• to learn specific functions of genes and what they determine

• to help patients decide whether or not to be tested

• to bind primers to the DNA template

What is a genetic counselor?

• A counselor who helps patients identify the risks of disorders.

• A counselor who treats psychological issues related to family.

• A counselor who suggests potential career paths for students.

• A counselor who helps people with physical, mental, developmental, or emotional disabilities live independently.

Which genetic test uses chemicals in the amniotic fluid to determine abnormalities in a fetus?

• carrier screening

• PGD

• ultrasonography

• amniocentesis

Which genetic test analyzes a neonate's blood to prevent disability or death?

• amniocentesis

• newborn screening

• CVS

• carrier screening

What is the goal of PCR?

• to make no copies of DNA

• to make millions of copies of DNA over a long period of time

• to make a few copies of DNA over a short time period

• to make millions of copies of DNA over a short time period

What happens in the initialization step of PCR?

• hydrogen bonds are broken and DNA is separated

• DNA polymerase is activated and contaminates are denatured

• a new strand of DNA is synthesized by the polymerase

• primers are binded to the DNA template

What happens in the denaturation step of PCR?

• hydrogen bonds are broken and DNA is separated

• primers are binded to the DNA template

• DNA polymerase are activated and contaminates are denatured

• a new strand of DNA is synthesized by the polymerase

What happens in the elongation step of PCR?

• DNA polymerase is activated and contaminates are denatured

• hydrogen bonds are broken and DNA is separated

• a new strand of DNA is synthesized by the polymerase

• primers bind to the DNA template

What are SNPs?

• single nucleotide polymorphisms that make copies of DNA

• single nucleotide polymorphisms that cause differences in traits

• single nucleotide polymorphisms that speed up reactions

• single nucleotide polymorphisms that break hydrogen bonds
