Transcription & Translation: Transcription (Basic) 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. Rna Transcription VideoMar 02, 2016 And one of the functions that RNA plays is to be that messenger, that messenger between a certain section of DNA and kind of what goes on outside of the nucleus, so that that can be translated into an actual protein. So the step that you go from DNA to mRNA, messenger RNA, is called. Custom mRNA Synthesis. Wide range of transcription RNA synthesis scales yielding µgrams to hundreds of milligrams. Fully traceable documentation system. In a transcription reaction, an RNA polymerase produces many copies of RNA by transcribing a DNA template which encodes the RNA. ![]() Once the contact is made, the RNA polymerase races along the DNA to transcribe the gene. Duration: 1 minutes, 52 seconds. Transcript: What you are about to see is DNA's most extraordinary secret—how a simple code is turned into flesh and blood. It begins with a bundle of factors assembling at the start of a gene. A gene is simply a length of DNA instructions stretching away to the left. The assembled factors trigger the first phase of the process, reading off the information that will be needed to make the protein. Everything is ready to roll: three, two, one, GO!
