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.

- . Discuss how mutations may arise in DNA, and the potential consequences for gene function if a point mutation were to occur in (a) the coding region of a gene, and (b) the non-coding regulatory region of a gene.arrow_forward. One way to determine where inside a cell a protein(protein X) normally localizes is to generate a reportergene construct containing: (i) the gene X regulatoryregion and coding sequences, and (ii) coding sequencesfor GFP fused in frame to the 3′ end of the gene Xcoding sequences just before the stop codon. A mousecontaining such a transgene will express a hybrid protein X-GFP only in those cells in which gene X is normally expressed.a. The gene X-GFP fusion gene described could begenerated by knocking in GFP coding sequencesinstead of by random insertion of a transgene.Diagram the knockin construct you could use forthis purpose.b. What might the advantage be of the knockin strategy versus the transgene strategy?arrow_forwardQ. Deletion of a single AT base pair from codon number 4 can cause a frameshift mutation in a protein-coding gene. Which of the following additional mutations will restore the reading frame back to “normal” such that the original stop codon will still function? (Note that the amino acid sequence will not necessarily be restored back to normal). Adding a base pair into each of the next two codons. Adding a GC base pair back in where the AT pair was deleted. Adding one base to the next codon and deleting one base from the one after that. Deleting a base pair from each of the next two codons. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E.
