Chapter 16, Problem 7A
A mechanism of control in E. coli not discussed in this chapter involves pausing of ribosomes allowing a transcription terminator to form in the mRNA. In eukaryotic fission yeast, this mechanism should
a. be common since they are unicellular.
b. not be common since they are unicellular.
c. not occur as transcription occurs in the nucleus and translation in the cytoplasm.
d. not occur due to possibility of alternative splicing.

- Below is a graphical representation of eukaryotic precursor mRNA. A. Outline each modification that must happen to get a mature m-RNA. B. How does the absence of introns in prokaryotic genes affect prokaryotic gene expression? C. How will gene expression be affected if all of the spliceosomes are removed from the bacteria sample? Explain.arrow_forwardIf a mutation occurred in a control element sequence associated with a particular gene, which of the following would be a likely consequence of this? A. This mutation is not likely to affect the expression of the associated gene, because RNA polymerase does not bind to control elements. B. This will likely affect the expression of the associated gene because it will loosen the coiling of chromatin at this site. C. The expression of the associated gene will be affected because this change will result in a nonsense mutation. D. This mutation is not likely to affect the expression of the associated gene, since control elements are noncoding sequences. E. The associated gene's expression would likely be affected, since this mutation would change the ability of at least one transcription factor to bind.arrow_forwardA protein is normally secreted from the cell. A team of scientists attempts to redirect this protein to the inside of the nucleus by mutating the sequence of the gene. Unfortunately, after this mutation, the protein is no longer secreted, but it is now localized to the cytosol and not the nucleus. Briefly answer the two questions below: a. Identify the sequence that was mutated by the scientists and explain your reasoning. b. What additional mutation must be made by the scientists to redirect this protein to the nucleus? Explain your reasoningarrow_forward

A possible way this inhibition may be relieved by an sRNA would be: Group of answer choices a)The sRNA acts as a silencer, suppressing the inhibitory protein and allowing translation to take place. b)The sRNA acts as a decoy, sequestering the inhibitory protein and allowing translation to take place. c)The sRNA acts as a marker, flagging the inhibitory protein for ubiquitination and allowing translation to take place.arrow_forwardWhat are two reasons that a eukaryotic gene (e.g. Green Fluorescent Protein in jellyfish) will not be expressed if it is inserted into a bacterial genome with no alterations? a.
