Summary Introduction
Introduction: Eukaryotic gene expression is a process where the proteins are expressed and regulated in the eukaryotic cell. In a developing stage, the embryo differentiates its cells into specialized cell types based on the protein expressed in them. A control over the eukaryotic gene drives the embryonic development.
