Abstract

Transcription activation is the first step in eukaryotic gene expression. Gene regulation, which is about turning on and off expression of specific protein-coding genes in response to environmental changes, during development and in differentiated cells, widely occurs at the level of transcription activation. This is mostly achieved by DNA-binding proteins that can control the specificity of the RNA polymerase II enzyme.
