Which of the following scenarios correctly describes a relationship between mRNA decay and protein abundance? A. A decrease in transcription with an increase in the rate of mRNA decay can result in increased protein abundance. B. An increase in transcription with an increase in the rate of mRNA decay can result in no change in protein abundance. C. An increase rate of protein synthesis but failure to form an apoprotein can be explained by a decrease in mRNA decay. D.

- The previously accepted model of the chloramphenicol action was that it inhibited all ribosomes equally. Why were the authors of the Marks, 2016 paper skeptical of this model? Choose all that are correct. Because they had observed that certain bacteria were resistant to chloramphenicol, and this proves that chloramphenicol stalls ribosomes at certain sites within those bacteria. Because certain MRNA templates had been observed to be inhibited by chloramphenicol more strongly than others Because chloramphenicol induces expression of chloramphenicol resistance proteins through translational arrest at specific codons in the leader ORFS of chloramphenicol resistance genes, which suggests there is preferential stalling at certain sites. Because chloramphenicol induces expression of chloramphenicol resistance proteins - therefore, these proteins must be able to be translated during chloramphenicol treatment. Because chloramphenicol binds the decoding center of the 30S subunit, and there are…arrow_forwardhelp please !!!! thank you in advancearrow_forwardE30. An electrophoretic mobility shift assay can be used to study the binding of proteins to a segment of DNA. In the experiment shown here, an EMSA was used to examine the requirements for the bind- ing of RNA polymerase II (from eukaryotic cells) to the promoter of a protein-encoding gene. The assembly of general transcription factors and RNA polymerase II at the core promoter is described in Chapter 12 (Figure 12.14). In this experiment, the segment of DNA containing a promoter sequence was 1100 bp in length. The fragment was mixed with various combinations of proteins and then subjected to an EMSA.
