- 4) Suppose you have an E. coli in which the gene that codes for the lac repressor protein has been mutated in such a way that the protein produced can bind to both lactose and DNA (at its specific binding site in the lac operon promoter) simultaneously. What effect, if any, would this have on regulation of expression of the lac operon? Briefly (1 sentence) explain why you would predict the effect or lack of effect this mutation would have.arrow_forwardCan you help me with this question? Im confused with the answer c or earrow_forwardConsider the lac operon of E. coli. Specifically, explain the following: a. Describe the overall chromosomal structure/organization of the operon, indicating the location and function of the regulatory regions and the structural genes. b. Is lac a catabolic or anabolic pathway? Explain. Is the operon inducible or repressible? Explain. c. Describe the mechanisms involved in negative control & positive controlarrow_forward
- For the trp operon, determine whether genes will be expressed (on) or silenced (off) given the following: a. Tryptophan levels are high. b. The trp repressor can no longer bind tryptophan.arrow_forwardYour investors are concerned that the GasP protein might not be sufficiently produced under normal laboratory conditions. They suggest controlling the transcription of the gasP gene using a chemical that will “trigger” its transcription. a. What type of promoter could be used? b. What chemical will you use to control transcription? c. How does this method of control work?arrow_forwardExplain Pleasearrow_forward
- Explain how the lac operon is regulated under the following conditions. Include the following terms in your answers: Repressor, Operator, RNA polymerase, CAP site, CAP protein, Promoter A. Lactose and glucose are both present. B. Lactose and glucose are both absent. C. Lactose is present and glucose is absent.arrow_forward6) The C-terminal domain (CTD) of yeast RNA polymerase II (RPB) subunit RPB1 contains the repeating amino acid sequence "-PTSPSYS-". Explain how this sequence plays a role in the regulation of the transcriptional activity of the yeast RPB holoenzyme.arrow_forwardConsider a mutation in -10 BOX promoter consensus sequence (TATAAT) in the prokaryote recA gene where the first T base mutated to G, what outcome(s) are likely? a. transcription levels will increase as the GC content would increase b. this mutation is silent, so no change in transcription level c. transcription levels would decrease because the promoter would be weaker d. transcription levels do not depend on the promoter sequence for the gal gene e. nothing would happen because the promoter would not change the mRNA sequencearrow_forward
- Mutations in the genes of the lac operon might affect the regulation of β-galactosidase synthesis. For each mutation listed below, indicating whether β-galactosidase would be regulated normally, always ON or always OFF. a. Mutation in operator site prevents repressor binding b. Mutation in lacIgene prevents repressor from binding operator c. Mutation in lacIgene prevents repressor from binding allolactose d. Nonsense mutation in lacZgenerearrow_forwardPredict and explain the effect on GAL1 transcription, in the presence of galactose alone, of the following mutations:a. Deletion of one Gal4-binding site in the GAL1 UAS element.b. Deletion of all four Gal4-binding sites in the GAL1 UAS element.c. Deletion of the Mig1-binding site upstream of GAL1.d. Deletion of the Gal4 activation domain.e. Deletion of the GAL80 gene.f. Deletion of the GAL1 promoter.g. Deletion of the GAL3 gene.arrow_forwardYou are growing E. coli in a laboratory in order to study their operons. The growth media you are using contains lactose, no glucose and no tryptophan. Using your knowledge of operons and their regulation a.Which operons would be functional under these conditions? b.What repressors would be made? (NOTE: name the repressors using their gene names) c.Which repressor(s) would be made in the inactive form? d.Which repressor(s) would be made in the active form? e.Which repressor(s) under these conditions can bind the operator sequence? f.Which repressor(s)under these conditions cannot bind the operator sequence?arrow_forward
