Summary Introduction
Concept 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. Genes are the fundamental units of heredity, which are composed of DNA. Each gene specifies a particular protein. For this, the genes will be converted into a useful product through the process of gene expression. Gene expression involves the conversion of DNA into RNA through the process of transcription. Then, this RNA will be converted into proteins through the process of translation.
