True or False? Mutations are never introduced during normal cellular processes in the eukaryotic cell.
Considering prokaryotes, what is the enzyme that removes the RNA primer and replaces it with newly synthesized DNA?
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.

- Various strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.arrow_forwardIn the: Exposure to a substance that mutates the Shine-Dalgarno sequence.

- Using the question in the image below, identify the locations of each mutation in strains 1, 2, and 3arrow_forwardTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. It is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. What is the difference between Rho Dependent and Rho Independent termination in prokaryotes?arrow_forwardWhy 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_forward
