How is gene expression a regulated process

Web16 sep. 2024 · September 16, 2024 by Alexander Johnson. Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made. Table of Contents show. WebThis process is tightly regulated, and inhibition of the machinery responsible for establishing these patterns results in abnormal development and, eventually, death of the organism. Important examples of the role of DNA methylation in gene expression during early development include X-chromosome inactivation, genomic imprinting, and the …
