Promoters are the regulatory DNA sequences positioned on the upstream region of a gene I e towards the 5' end. These promoters are responsible for promoting the transcription of a gene. Transcription factors( in eukaryotes) have the ability to recognise these promoter sequences and after attaching to them, they recruit the polymerase enzyme which starts the transcription. The transcription starts from the +1 transcription start site after binding to the promoter region. The promoter region is not transcribed into mRNA. For example, Pribnow box is a prokaryotic promoter region, whereas TATA box is a eukaryotic promoter region.
Hence, the promoter is the correct answer.

1. Molecular cloning has made it possible to take a DNA fragment from nuclear DNA, containing an entire gene, and insert it into a cloning plasmid just behind a phage promoter. This means that the cloned gene can be transcribed in a test tube using a commercially available phage RNA polymerase protein. If you were to use agarose gel electrophoresis to separate RNA according to size, would the RNA produced in the test tube show any differences with RNA from...
