What is the role of dna in the process of transcription of messenger rna?

Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production. Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA (in red). Here, two transcription factors are already bound to the promoter. Other proteins arrive, carrying the enzyme RNA polymerase (in blue). To initiate transcription, these assembled proteins require contact with activator proteins that bind to specific sequences of DNA known as enhancer regions. Once the contact is made, the RNA polymerase races along the DNA to transcribe the genehttps://www.dnalc.org/view/15510-Transcription-DNA-codes-for-messenger-RNA-mRNA-3D-animation-with-ba...
