Transcription proceeds when RNA polymerase?
Attaches to a promoter molecule.
What is the region of DNA where RNA synthesis begins called?
The region of DNA where RNA synthesis begins is the promoter. DNA contains a number of upstream regulatory and promoter sequences but the region of DNA where RNA synthesis begins is the start codon. This is the first codon that translates into an RNA nucleotide.
The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a?
promoter
What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
List three parts of the gene that researchers look for?
If you mean "DNA molecule", it would be phosphate, sugar and either of these 4 adenine, thymine, guanine or cytosine. If you do mean gene, then the parts are the Promoter (which starts the gene and gives instructions for when and how the gen should be used), the coding sequence (which creates a protein), and the terminator (which stops the creation of a protein).
Examples of a molecule in your body that can affect transcription factors?
A repressor, which works by binding to the operator and blocking the attachment of RNA polymerase to the promoter.

What is The opposite meaning of Promoter?
promoter
What event in transcription initiation likely occurs last?
The binding of RNA polymerase to the promoter sequence is the likely event that occurs last in transcription initiation. This binding allows for the initiation of RNA synthesis and the subsequent elongation of the RNA molecule.
What environmental factor causes the lac operon to turn on?
In the lac operon model, lactose acts as in inducer molecule. In the presence of lactose, the molecule binds to the repressor protein. This repressor-lactose complex is unable to bind to the promoter. When the promoter is not occupied, RNA pol - II binds to it and begins transcribing the structural genes located downstream. Thus, the lac operon is turned on in the presence of lactose.
