What is the ultimate parasite and why? |
the virus because they are not true organisms and absolutely cannot live alone |
|
How does the protein gene coding density of a virus compare to that of a eukaryote? |
the protein gene coding density of a virus is much denser than that of a eukaryote |
|
What type of virus, in regards to its lifecycle, would you use to develop for a treatment to kill bacteria? |
bacteriophages can be used to kill bacteria |
|
Is a virus that infections fish likely to infect you? Why or why not? |
it is possible for a virus to spread from a fish to you if you are directly handling the animal because the fish could have a zoonotic virus which can be spread from animals to humans. |
|
Which part or step in the viral infection pathway is most specific and a logical target for antiviral drugs? |
the attachment to host-specific cells |
|
When are viruses usually the most pathogenic to the host? |
when it infects the new host species |
|
Can diseases be transmitted by "naked" polymers of biological molecules (i.e. not packed in something or a cell membrane)? |
yes they can |
|
Of all the disease causing particles/organisms, which mutates the fastest? |
viroids |
|
What are the three domains of life? |
bacteria, eukarya, and archaea |
|
What cell structure allows prokaryotes to live in hypotonic (low salt) environments? |
peptidoglycan cell wall |
|
What is a storage or hibernating form of some prokaryotes, protists, and fungi that allows for dispersal of the organism by wind and water? |
spores |
|
What are the three types of cellular appendages that many microorganism use to move about in water or on the surface of materials? |
flagella, pili, or slime nozzles |
|
Which types of photosynthetic bacteria grow on the sides of houses and roof shingles, typically leaving a green stain on the house? |
cyanobacteria |
|
For bacteria, what are different mechanisms of lateral gene transfer and which is the least specific? |
Genome and plasmids, conjugations, transformation, and transduction. Transformation is the least specific. |
|
How does a bacterial infection differ from a bacterial intoxication? |
A bacterial infection is caused because of organism presence and number whereas bacterial intoxication is caused by the organism producing toxins that kill or maim host cells. |
|
What phenomenon is a wonderful example of the role of lateral gene transfer in evolution that is especially observed in a hospital environment and demonstrates that hospital staff are not necessarily well trained in containing highly infectious diseases? |
drug-resistant bacteria |
|
Of the prokaryotes, organisms in which domain are most likely to survive in the harshest environment? |
archaea |
|
If you were going to start a business that mined genomes for protein coding genes of technological value, which domain of life would you focus and why? |
archaea |
