The earliest known regulators of gene expression were proteins known as repressors and activators – regulators with specific short binding sites within enhancer regions near the genes to be regulated. Later studies have shown that RNAs also regulate genes. There are several kinds of RNA-dependent processes in eukaryotes regulating the expression of genes at various points, such as RNAi repressing genes post-transcriptionally, long non-coding RNAs shutting down block… WitrynaControl of Gene Expression in Prokaryotes How do prokaryotes use operons to.

RNA localization in prokaryotes: Where, when, how, and why

WitrynaProkaryotes are small, single-celled living organisms. Since prokaryotic cells do not have a nucleus or organelles, gene expression happens out in the open cytoplasm, and all the stages can happen simultaneously. Controlling gene expression is crucial for their cellular behavior.
