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.


Does eukaryotic transcription begin before the promoter clearance?

No, Eukayotic transcription begins after promoter clearance. Promoter clearance just prepares the transcription initiation complex to begin elongation. Promoter clearance does not produce any functional gene.


What is the region where RNA polymerase binds on DNA?

The transcription initiation complex around the TATA box.


Does a promoter determine whether a gene is expressed?

No it does not a promoter is a binding site for RNA polymerase.


What is the function of the TATA box?

The TATA box assists in directing RNA polymerase II to the initiation site downstream on DNA. RNA polymerases bind to regions of DNA known as promoters. Promoter regions are comprised of the initiation site and numerous nucleotides upstream from the initiation site. The TATA box is necessary for transcription because RNA polymersase II cannot recognize the initiation sites on its own.


What site of initiation of the defecation reflex?

the anus


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.


Which step in what procedure represents transcription?

Transcription is the process of synthesizing messenger RNA (mRNA) from DNA. It occurs in the nucleus of the cell and involves three main steps: initiation, elongation, and termination. The initiation step involves the binding of RNA polymerase to the promoter region of the DNA.


What process begins at the promoter of DNA?

The promoter is the sight at which the transcription machinery binds the DNA and initiates the transcription of the gene.


How is a promoter region different from an operator region?

A promoter region is different from an operator region in the sense that the operator region is where DNA binds, whereas the promoter region is the binding site for the RNA polymerase. These two different regions are essentially opposites.


The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a?

promoter


What is a collective name for a group of genes involved in the same function their promoter site and their operator?

Operon
