Textbook Question
Chapter 19.4, Problem 4RIA
You are building a tree based on 16S rRNA sequence alignments of a group of spirochetes. Suggest a possible outgroup so that you can build a rooted tree. Refer to chapter 21 if you need more information about these bacteria.

Consider the fact that the use of 16S rRNA sequencing as a taxonomic and phylogenetic tool has resulted in tripling the number of bacterial phyla. Why has the advent of this genetic technique expanded the currently accepted number of microbial phyla?
Bergey’s Manual of Systems Bacteriology provides information on classifying bacteria according to rRNA.

Why did Carl Woese propose the domain Archaea?
The domain Bacteria already had too many organisms in its classification.
The methanogens were discovered to be a complex organism, between prokaryotic bacteria and eukaryotes, thus it needed its own domain.
He discovered that methanogens were too large to be classified as bacteria, but too small to be classified as Eukarya.
In analyzing the rRNA of methanogens, he discovered that it was completely distinct from any other bacterial RRNA that had been studied.
The DNA of methanogens was discovered to use different nucleotides than those of organisms in Eukarya or Bacteria.

- For this assignment you will create a dichotomous key to help you Identify Bacteria (which are a pain in the bum to identify on the species level.) We will be focused on the general terms of bacteria and the only Phylum that will be addressed is the Cyanobacteria. Use the following to create a dichotomous key to begin to identify Bacteria: BACTERIA Bacillus Coccus Spirillium Phylum Cyanobacteria Gram (+) (-) Root nodules To Begin use the following question: Does the organism exhibit a membrane bound nucleus?arrow_forwardImagine that you discover a new type of bacteria in an environment that is exposed to oxygen. A. What type of bacteria might you have discovered? B.

- What are the 4 characteristics/properties of rRNA genes which make them good molecular chronometers. Why viruses are not found in the tree of life? Why might viable cell cultures be of more use in microbial taxonomy than preserved specimens? Is it possible to provide a formal name for a microorganism that has not been cultivated in isolation? What kind of name might be used if a microorganism is well-characterized but cannot yet be cultivated in isolation?arrow_forwardAccording to Philip Bell’s viral eukaryogenesis hypothesis, genes for DNA replication, RNA transcription, protein translation, and histone proteins were all provided by: an endosymbiotic gram-negative eubacterium an endosymbiotic archaeobacterium a gram-positive eubacterial host cell a double-stranded DNA virus an archaeobacterial host cellarrow_forwardDescribe the relationship between the original bacteria kingdom called monera and the domain called bacteria.arrow_forward
- Give an example of a gene sequence that can be used to classify some bacterial or eukaryotic species.arrow_forwardRickettsia bacteria always lives as parasites inside eukaryotic cells, ad their genomes are much smaller then those of free living bacteria. Organisms that live only as parasites often have reduced genomes compared to the free living relatives. How could a parasitic lyfestyle contribute to a reduction in genome size?arrow_forwardWhat problem with the six-kingdom classification system was addressed by the three-domain classification system?

- Is there such a thing as a “good virus”? Explain why or why not. Considerboth bacteriophages and viruses of eukaryotic organisms.arrow_forwardIn 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?arrow_forwardA sample of bacteria is collected from soil in a field that was recently treated with pesticides. The bacteria are classified and a phylogenetic is built to illustrate the soil bacteria diversity. What kinds of characteristics would be best for creating this phylogenetic? a. rRNA gene sequence and amino acid sequence of lipase b. Cell wall structure and physical appearance c. Reproductive rate and susceptibility to pesticides d. Entire genome sequence and protein expression dataarrow_forward
