Gene expression is the process by which information from a gene is used in the synthesis of a protein. One of the interesting examples is the synthesis of insulin. Every time you eat, the increase of nutrients in the blood is sensed by pancreatic beta cells that, in response, synthesize and secrete insulin. Initially, the insulin gene, INS, is ___________________. At this point, mRNA is exported from the ________________ into the cytosol, via the ____________________.

Insulin
