Directiоn: Cоrtisоl is а signаling molecule thаt regulates gene expression in the cells of a mammal. Cortisol enters a cell and binds to a protein called a cortisol receptor. Binding of cortisol facilitates the phosphorylation of the cortisol receptor, which then can enter the nucleus and affect transcription. The figure below shows a system of two genes whose transcription is regulated by cortisol: IL10 and BGLAP. The IL10 gene codes for a protein called interleukin 10. The BGLAP gene codes for a protein called osteocalcin. A cortisol receptor can activate or repress the transcription of a gene, depending on the structure of the gene's regulatory element. For example, a cortisol receptor activates transcription of the IL10 gene but represses transcription of the BGLAP gene. A researcher removed these genes from cells and placed them in chemical solutions with specific concentrations of cortisol. All solutions contained high concentrations of the cortisol receptor and RNA polymerase. The figure below shows the data resulting from the experiment. Each graph shows the relative abundance of mRNA in the presence or absence of cortisol. The graph on the left shows the effect of cortisol on the expression of the IL10 gene. The graph on the right shows the effect of cortisol on the expression of the BGLAP gene. The researcher repeated the experiment with genes that contain a mutation. The figure below shows the results of this new experiment. Which region of the lac operon contains the mutation?
