- 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_forwardIn the presence of cephalosphorin, what will be the protein product of the prokaryotic cell gene shown below? 5'-CATGTCAGTAAGGCATCT-3' (Assume this is a segment of a larger structural gene that will be translated into protein in its entirety.)arrow_forward
- Genetic 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 might be some potential reasons for this evolutionary decay of its genome?arrow_forwardProvide a detailed description of gene expression and control in prokaryotes. Provide a detailed description of proteins critical for this process. (please hand draw a figure showing gene expression and control in prokaryotes and the proteins involved)arrow_forwardUsing a computer algorithm that searches for sequence similarities in other organisms, you discover that hexose kinase is a highly conserved gene that is expressed by many species, both prokaryotic and eukaryotic. The most closely related prokaryotic homolog of hexose kinase has a protein sequence in which 90% of the amino acids are identical to those of the human version of the gene. To learn more about their similarity at the DNA level, you obtain segments of the genomic DNA coding for the hexose kinase gene in both humans and this prokaryotic species. After combining both DNA samples, you heat them to denature the DNA strands and then allow them to cool and reanneal. Finally, you examine the DNA hybrids you obtain under the electron microscope. Your analysis reveals that there are three different DNA hybrids in this sample, these can be seen below. You reason that one must belong to the prokaryotic species, one to the humans and the third arose when one strand from each species base…arrow_forward
- You and your fellow researchers want to make bacteria glow using a eukaryotic gene that results in bioluminescence. 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_forwardSome 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_forward

The gene contains a complete promoter, polyadenylation sequence and a wildtype nucleotide sequence.
