Control of gene expression in prokaryotes and eukaryotes
... Gene expression is transcription of DNA to make RNA and then using the RNA to make proteins. This process can’t be left on indefinitely. The turning on and off of genes is critical to the development of an organism and the organism functioning properly throughout its life. Eukaryotic control Pretran ...
