Unformatted text preview: The process of protein synthesis. After the protein has been synthesized completely, it is removed from the ribosome for further processing and to perform its function. For example, the protein may be stored in the Golgi body before being released by the cell, or it may be stored in the lysosome as a digestive enzyme. Also, a protein may be used in the cell as a structural component, or it may be released as a hormone, such as insulin. After synthesis, the mRNA molecule breaks up and the nucleotides return to the nucleus. The tRNA molecules return to the cytoplasm to unite with fresh molecules of amino acids, and the ribosome awaits the arrival of a new mRNA molecule. Gene control The process of protein synthesis does not occur constantly in the cell. Rather, it occurs at intervals followed by periods of genetic “silence.” Thus the cell regulates and controls at intervals followed by periods of genetic “silence....
