What is The nontranscribed region of DNA to which RNA polymerase binds to initiate transcription called?
promoter
The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a?
promoter
What is the attachment site for RNA polymerase?
according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA. The factor 'sigma' will only attach itself to the complex DNA / RNA polymerase when the RNA polymerase is attached to a promoter. Another hypothesis is that the factor sigma attaches to RNApol anyway and the enzyme is then able to slide along the DNA until it finds a promoter. It prevents detaching and speeds up promoter location, and decreases the affinity of RNApol for general regions of DNA. " Therefore, the answer seems to be, RNA attaches to DNA through a small protein called the factor sigma once the RNA polymerase attaches itself to a chain sequence called a "promoter". according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA.

Actually there are many promoter and many genes but which gene to be transcribed is decided by sigma factor.
How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What are the proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter called?
transcription factor
Proeteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
inducer
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
What is The nontranscribed region of DNA to which RNA polymerase binds to initiate transcription called?
promoter
The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a?
promoter
What do the promoter region do in the DNA translation?
The promoter region has no role in translation. It is the site where RNA Polymerase binds to initiate transcription. Basically, talking about bacteria, a protein called sigma70 binds to the promoter and recruits the RNA Polymerase enzyme. After the RNA Pol is recruited, the sigma70 factor is released and RNA Polymerase synthesizes the complementary mRNA from the DNA that is being transcribed.

Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
What is the process called where protein synthesis starts in the ribosomes?
Protein synthesis when RNA polymerase attaches to the DNA at a specific area called the promoter region. The information in DNA is not directly converted into proteins, but must first be copied into RNA. This ensures that the information contained within the DNA does not become tainted.
What is initiation in transcription?
So in Transcription there are three main steps: Initiation, elongation and termination. The one I'm focusing on is Initiation. In eukaryote, proteins called transcription factors mediate the initiation of transcription by RNA Polymerse II. A eukaryotic promoter commonly includes a TATA box, a nucleotide sequence containing "Thymine-Adenine-thymine-adenine", about 25 nucleotides upstream from the transcriptional start point.
What happens at the end of the transcription from DNA to Protein?
The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
