How do eukaryotic cells regulate genes

WebBoth prokaryotic and eukaryotic cells have ways of co-regulating genes, but they use very different mechanisms to accomplish this goal. In prokaryotes, co-regulated genes are typically organized into an operon, where two or more functionally related genes are transcribed together from a single promoter into one long mRNA. WebNov 8, 2024 · Estrogen is a signal that bone cells need in order to work properly. When these cells detect estrogen, they increase expression of genes impacting how the cell uses fuel and generates energy. 2 This helps these cells mature and promote bone maintenance. Not all of estrogen’s impacts on gene expression promote our health though.
