Eukaryotic Gene Regulation Transcription factors are DNA-binding proteins. They control the expression of genes in eukaryotes by binding DNA sequences in the regulatory regions. Gene promoters have multiple binding sites for transcription factors, each of which can influence transcription.

To understand the control of gene expression, two key concepts should be understood. First, gene expression requires transcription , the process of making a messenger ribonucleic acid (mRNA) copy of the deoxyribonucleic acid (DNA) gene.
