Emotion regulation through the ages 123. between the limbic system and the outer layers of the cortex, in which limbic reso-. nance guides focused perception and reappraisal (Lewis et al. in press; Tucker 2001).
Diagram showing at which stages in the DNA-mRNA-protein pathway expression can be controlled. Regulation of gene expression includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA), and is informally termed gene regulation. Repressors bind to the Operator, coding sequences on the DNA strand that are close to or overlapping the promoter region, impeding RNA polymerase's progress along the strand, thus impeding the expression of the gene.The image to the right demonstrates regulation by a repressor in the lac operon.
