A hormone is a chemical that is produced in one part of the body, travels through the blood and affects cells in other parts of the body. Many hormones are proteins. How might the production of a hormone affect the expression of genes in a eukaryotic cell? Write a hypothesis that could be tested to answer this question. (Hint: Include promoters in your hypothesis.)
