In this article we will discuss about the details of structural genes. Structural Genes: They control amino acid sequence of a protein by producing mRNA. There are as many structural genes as there are proteins which are regulated. Either a single mRNA is transcribed from each structural gene or, all the structural genes of an operon form a single polycistronic [...]

Epigenetic Control of Genetic Regulation. The Inducible [...]
In this article we will discuss about the Transcriptional and Post-Transcriptional Regulation of Gene Expression in Eukaryotes. Transcriptional Regulation of Gene Expression in Eukaryotes: The variation in the rate of transcription often regulates gene expression. Interactions between RNA polymerase II and basal transÂcription factors leading to the formation of the transcription initiation complex influence the rate of transcription. Other transcription [...]
