WebDNA is the molecule which controls the synthesis of proteins. Proteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities. Thus DNA is able to exert a controlling influence over the whole cell and ultimately, the whole organism. 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.
