WebThey are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein. Upstream of … WebThe process of protein synthesis does not occur constantly in the cell, but rather at intervals followed by periods of genetic “silence.” Thus, the process of gene expression is regulated and controlled by the cell. The control of gene expression can occur at several levels in the cell. For example, genes rarely operate during mitosis.
