Indiscriminate examination of members of a population to detect heterozygotes of serious disorders | Carrier Screening |
These types of disorders are seen in recognizable patterns, genetic testing looks at a genotype to determine if some one has a disorder, will develop one or is a carrier | Single Gene |
The complement of an organism’s genes; an organisms genetic material is known as: | Genome |
segment of DNA that contains instructions for the production of a protein is a(n) | Gene |
A display of chromosome pairs of a cell arranged by size and shape is a(n) | Karyotype |
Gene therapy is | the alteration of genes of person that has a genetic disorder |
recognizes specific DNA sequences and cuts DNA | Restriction Enzyme |
The process where the double strands of DNA seperate is called | Denaturation |
an example of gene therapy technology | development of a nasal spray that contains copies of the normal gene that is defective in persons with cystic fibrosis |
A procedure in which gametes are fertilized in a dish in the laboratory, and the resulting zygote is implanted in the uterus for development | In Vitro Fertilization |
If a restriction enzyme were to cut a strand of DNA three times, how many RFLPs would show up on a gel | 4 |
DNA was compared between two people. The comparison revealed the presence of a T instead of an A at one location. What can be said about the two DNA segments | They contain a SNP |
A person does not show any signs of having a disorder that runs in their family. What is the best way to determine if this person is heterozygous for this disorder | Carrier Screening |
A woman is pregnant with her third child. Her doctor is concerned that the fetus may have an extra chromosome 21. What would be the best method to determine if this is true | make a karyotype |
The gene-specific primers used in PCR allow amplification when they | anneal to the DNA |
What is used to visualize and determine a genotype | gel electrophoresis |
duschene muscular dystrophy is what kind of disorder | Sex-Linked |
cystic fibrosis is what kind of disorder | Autosomal Recessive |
huntington’s disease is what kind of disorder | Autosomal Dominant |
down syndrome is what kind of disorder | Chromosomal |
leber optic neuropathy is what kind of disorder | Mitochondrial |
alzheimer’s is what kind of disorder | Chromosomal |
retrovirus carries what kind of genetic material | RNA |
adeno-associated virus carries what kind of genetic material | Single-Stranded DNA |
adenovarus carries what kind of genetic material | Double-Stranded DNA |
naked DNA carries what kind of genetic material | Single-Stranded DNA |
herpes simplex virus carries what kind of genetic material | Circular Double-Stranded DNA |
liposome carries what kind of genetic material | Circular Double-Stranded DNA |
In assisted reproductive technology, the determination of genetic abnormalities in the embryo before it is transferred to the uterus is known as | Preimplantation Genetic Diagnosis (PGD) |
Karyotypes of an individual are an important diagnostic tool in for these type of disorders. | Chromosomal |
Parts of the human genome that vary by one nucleotide are called | SNP's |
Which of the following is NOT a key of successful gene delivery | Choosing the proper chromosomes |
. A small amount of fluid is withdrawn from a pregnant women’s uterus. The fluid is used to monitor the health of her developing child. What test has been performed? | chorionic villus sampling |
Taq polymerase is used in PCR because it | catalyzes primer formation |
