Regulation of gene expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA).

All cells control or regulate the synthesis of proteins from information encoded in their DNA. The process of “turning on” a gene to produce mRNA and protein is called gene expression.

Describe mechanisms that regulate gene expression in eukaryotes, including promoter activity and chromatin structure. Explain when splicing occurs and how it contributes to mature mRNA formation. …

Aug 4, 2025 · Gene expression is governed by a layered system of regulation, stretching from the nucleus to the outer edges of the cell. Like a conductor managing an orchestra, the cell uses a …

Jun 10, 2025 · Gene expression is a highly orchestrated process that causes cells to adapt to changing environments and developmental needs. Regulatory proteins and small RNA molecules control when …

genes are only expressed when needed. Often regulated at transcription. The first system of gene regulation that was understood was the lac operon in E. coli, worked out by Francois Jacob and …

Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active …

This article looks at the many steps involved in controlling gene expression, from how tightly DNA is packed in the cell to how RNA is processed and proteins are made and modified.

Here we discuss the direct control of gene regulatory processes by metabolites and recent progresses that expand our abilities to systematically characterize metabolite-protein interaction networks. …

Aug 5, 2023 · Coordination of transcription and translation Although transcriptional regulation of mRNA production is primary in bacteria, regulation of ribosomal RNA (rRNA) and protein synthesis plays an …
