Textbook Question
Chapter 15, Problem 4S
There are a number of features that are unique 10 bacteria, and others that are unique to eukaryotes. Could any of these features offer the possibility to control gene expression in a way that is unique to either eukaryotes or bacteria?

Describe the unique feature that occurs exclusively in the gene regulation of eukaryotes.
Certain mutations called amber in bacteria and viruses result in premature termination of polypeptide chains during translation. Many amber mutationshave been detected at different points along the gene thatcodes for a head protein in phage T4. How might this system be further investigated to demonstrate and support the concept ofcolinearity?
Create a Venn diagram to compare and contrast the process of gene expression in Bacteria versus eukaryotes. Remember that “gene expression” can include any part of transcription or translation. Try to be as thorough as you can about what aspects of this process are similar between the two taxa, and what characteristics are distinct to only Bacteria or eukaryotes. Plase include a minimum of 15 items in the Venn diagram.

- Why is it easier to identify spontaneous mutations in bacteria than in most eukaryotes? The mutations occur at a much higher frequency. Because bacteria have smaller genomes. The mutations can be induced via exposure to the bacteriophage. The mutations are expressed directly in descendant cells because bacteria are haploid. The mutations are visible as color changes within a bacterial colony.arrow_forwardThe following is a difference between eukaryotic and prokaryotic gene regulation: O Only prokaryotes have operons O Only eukaryotes can regulate genes by altering chromatin structure O Only prokaryotes can have coordinated expression of several genes O Only eukaryotes have proteins that act as activators of transcriptionarrow_forwardGenetic analysis of Mycobacterium leprae, the bacterium that causes leprosy, reveals that its genome has undergone decay over time, losing DNA and acquiring mutations that make some of its genes nonfunctional.

What factors should you consider when attempting to express eukaryotic genes in prokaryotic cells before designing your experiment?arrow_forwardWhich of the following statements about the attempt to express a eukaryotic gene in bacteria is TRUE? Choose an answer below: The eukaryotic promoter will function in the bacterial cells. The transcript will be capped. Expression of the gene will always yield a functional protein. The stop codon of the eukaryotic gene will function in the bacterial cells. The transcript will be spliced the same way as in eukaryotic cells.arrow_forwardWhy do humans have such a large number of nucleotides (3.2 billion base pairs) compared to the number of nucleotides in the Japanese pufferfish (with only 400 million base pairs)? the difference is due primarily to a relative abundance of intron nucleotides in humans the difference is due primarily to a relative abundance of euchromatin sequences in humans the difference is due primarily to a relative abundance of intron sequences in humans the difference is due primarily to a relative abundance of protein-coding genes in humans the difference is due primarily to a relative abundance of exon sequences in humansarrow_forward
- Some bacteria might be able to respond to environmental stress by increasing the rate at which mutations occur during cell division. How might this be accomplished? Do you think there would be an evolutionary advantage of this ability? Explain.arrow_forwardThe figure below shows RNA-Seq data (RED) for the D. melanogaster transformer (tra) gene obtained from both adult female and male fruit flies. The blue lines indicate the tra gene structure, with thicker lines indicating exons, and thin lines introns. The 5' end of the gene is on the left, and the 3' end of the gene is on the right. Based on these data, the most likely conclusion is: Males and females express identical isoforms of tra Males express more tra RNA than females The female isoform has fewer amino acids The female isoform has more amino acids The male and female isoforms have different 3'UTRsarrow_forwardHow would you contrast gene regulation in prokaryotes with that in eukaryotes?arrow_forward
