Textbook Question
Chapter 26, Problem 14PIAT
MODEL Other hypotheses for the tree of life present the Archaea as the ancestors to all other organisms. Make a sketch of a phylogenetic tree that presents Bacteria and Eukarya as more closely related to each other than to Archaea, and has Archaea as a sister group to Bacteria and Eukarya.

Explain in which domain you would classify an organism that consists of a single cell with a nucleus.
make a drawing of a phylogenetic tree that contains all 3 domains of life. The tree should include at least
three different animals, two plants, chemoheterotrophic bacteria, photoautotrophic bacteria,
chemoheterotrophic archaea, thermophilic archaea and fungi. Identify both primary endosymbiosis events
on the tree and draw a line to connect it to the organism that would become the future organelle.
The universal phylogenetic tree of life shows the divergence of Bacteria, Archaea, and Eukarya. Studies of Lokiarchaeota help
to elucidate these relationships, but the first universal tree of life was constructed by Carl Woese using ribosomal RNA
sequences. There are advantages to using different types of nucleic acid for different types of analyses.
What is a specific advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic
analysis compared with DNA sequences?
▸ View Available Hint(s)
SSU rRNA sequences accumulate mutations more rapidly than protein-encoding DNA.
SSU rRNA is frequently transferred through horizontal gene transfer, whereas DNA sequences are not.
Primers are required in DNA sequence analysis, but not for SSU rRNA sequence analysis.
Although PCR products can be visualized with SSU rRNA, this is not the case with other forms of nucleic acids.
DNA sequences are too highly conserved to work well for sequence analysis; individual species are…

- This chapter shows a phylogenetic tree for the three domains of life, which is based on DNA sequence data for rRNA and other genes. Which of the following answers concerning the phylogenetic relationships found within this tree is incorrect? View Available Hint(s)for Part A Euryarcheotes are found in the Archaea Diatoms, Tubulinids, and Euglenozoans belong to the domain Eukarya Forams, Fungi, and Chlamydias belong to the domain Eukarya. Spirochetes belong to the domain Bacteria Ciliates, Red Algae, and Plants belong to the domain Eukarya.arrow_forwardThe TATA-binding protein (TBP) is thought to be necessary for transcription in all eukaryotic cell nuclei.

- Describe the evidence that supports the endosymbiotic theory of evolution of eukaryotes.arrow_forwardDescribe some of the hypotheses on the origin of life and the characteristics of early prokaryotes, eukaryotes, and multicellular organisms.arrow_forwardWhy 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.arrow_forward
