WebGene Expression - Key takeaways. Regulation of gene expression patterns in eukaryotic cells is a complex process that occurs at various levels, from elements within the DNA of modifications to complete proteins. Not every piece of DNA holds instructions to make a protein; some sequences exist to regulate the expression of other genes. WebAs with the epigenetic and transcriptional stages of processing, this post-transcriptional step can also be regulated to control gene expression in the cell. If the RNA is not processed, shuttled, or translated, then no protein will be synthesized. RNA splicing, the first stage of post-transcriptional regulation slow roasted italian website
