Explain one mechanism that eukaryotic organisms is to regulate genes.

Epigenetic regulation mechanism and Repressors and transcriptional activators allows eukaryotic organisms is to regulate genes.

Explanation:

The gene expression regulation process in eukaryotic cell is complicated than when compared to the gene expression regulation process. In the organisms like multicellular, the regulation of gene expression obtained by the proteins. The regulation of genes in this type of organisms doe not take single level of execution.

Before the transcription stage begins, the DNA access is initially regulated. This process of regulation is termed as epigenetic regulation. There are 20,000 genes that are encoded by the genomes in human beings. These are arranged in such a way that they will be used by the particular type of cells when there is any need.
