Archaeans are a group of prokaryotes that are similar to the eukaryota phylum. The archae includes organisms that are able to survive in extreme environments, like salt, high temperatures, and marshy lands. Unlike bacteria, the archaeans lack a peptidoglycan layer in their cell walls.

Question

Which of the following best describes the mechanism of action of the antibiotic streptomycin? A. it disrupts protein synthesis in resistant bacteria. B. Streptomycin inhibits cell wall synthesis in all bacterial species. C. Streptomycin creates mutations in bacteria which cause them to become resistant. D. It disrupts protein synthesis in nonresistant bacteria.

In 2006, the US Food and Drug Administration (FDA) approved the use of bacteriophage preparation that can be used on ready-to-eat meat and poultry products to kill Listeria monocytogenes, a bacterium that causes listeriosis. Some people may have concerns about the use of phages in foods. From what you have learned about bacteriophages and viruses, why do you think we do not have to be concerned about the presence of bacteriophages in food?

Analyses of genomes have allowed researchers to determine that some cells have very small genomes. If you were asked to predict which organisms are likely to have smaller genomes than others, which option below would be MOST likely? A. Bacteria that live in plant hosts are likely to have smaller genomes than those that live in animal hosts as it takes a smaller variety of metabolic processes to survive in an animal host. B. Although less is known about Archaea than about Bacteria as fewer species have been studied, it is likely that Archaea have smaller genomes on average than Bacteria as they have fewer metabolic needs. C. Bacteria that are endosymbionts, living within a host, can survive with smaller genomes than free-living Bacteria because they can rely on their host for many of their needs. D. Protists generally have had smaller genomes than Bacteria because Bacteria have such large amounts of noncoding DNA.
