b. agrobacterium tumefaciens
c. retrovirus
d. adenovirus
2. If you are working in the lab with the goal of identifying a short strand of nucleotides that can bind to Tau proteins, a family of pathogenic proteins implicated in cell death during the progression of Alzheimer's disease, what type of therapeutic would you be developing?
a. An antisense therapeutic
b. An antigene therapeutic
c. An aptimer
d. An antibody
3. Which of the following statements regarding the human genome project are true?
a. The human genome contains approximately 3 million basepairs.
b. The human genome project took approximately 3 years to complete and involved participation by more than 200 labs.
c. The human genome contains approximately 15,000 genes.
d. While the nucleotide sequence has been determined, the function of all of the genes in the genome is still an active area of research.
4. To develop a DNA vaccine against chicken flu virus. How would such a vaccine work?
a. Chickens infected with the flu would be given DNA that would compete with viral DNA.
b. Chickens would be given dead viruses to cause their bodies to produce antibodies that would then be effective against live viruses, should they ever encounter them.
c. Chickens would be given viral proteins to stimulate their immune systems to produce antibodies against the virus.
d. Chickens would be given DNA segments to cause the chickens to produce viral proteins, triggering a cellular and an antibody mediated immune response.
e. Chickens with the flu would be given DNA that would produce proteins that would fight the virus.
