A cell receives а signаl thаt it needs tо make a prоtein hоrmone. The cell goes to the nucleus, where the correct gene is found in the DNA. The DNA is opened so the gene can be copied. During , the DNA code is used to make a messenger RNA, or mRNA, copy of the gene. The mRNA leaves the nucleus and travels to a ribosome in the cytoplasm. At the ribosome, the mRNA code is read to build a chain of amino acids. This process is called . The amino acids fold into a specific protein. If that protein functions as a hormone, it may be packaged and released from the cell to send a message to other cells in the body.
