WebTo assemble your DNA model, lay two Twizzlers parallel to one another with about 8 cm of space in between. You will link the pairs of code chemicals to your DNA backbones by attaching each pair to the backbones so that the pair look like ladder rungs. Lay your pairs between the backbones, as shown below. WebRNA DNA polymerase is an enzyme that makes copies of the DNA sequence into RNA. Initiate transcription by recruiting and assisting RNA Polymerase, which muddles the promoter region. Transcription factors attach to the gene's promoter region to begin transcription. The promoter region marks the start of the gene's transcription process.
