The regiоn оf аn enzyme оn which substrаte binds to is cаlled the _______.
Cоrtisоl is а signаling mоlecule 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 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 next figure 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 last figure shows the results of this new experiment. Which statement accurately explains the pattern of transcription in the new experiment?

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. 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 by binding to a regulatory element. For example, a cortisol receptor activates transcription of the IL10 gene but represses transcription of the BGLAP gene. When a person experiences stress, their adrenal gland releases cortisol, increasing the concentration of cortisol throughout the body. As a person sleeps, the concentration of cortisol in their blood decreases to nearly zero. After waking, the concentration of cortisol increases by four to seven times the concentration during sleep. Which statement accurately describes the abundance of mRNA in a cell?
