Which process stop when rna polymerase comes to a terminator?

Transcription is the process that stops when RNA polymerase is terminated.


How does RNA polymerase determine its binding location on the DNA strand?

RNA polymerase determines its binding location on the DNA strand by recognizing specific sequences of nucleotides called promoter regions. These promoter regions contain signals that indicate where the RNA polymerase should start transcribing the DNA into RNA. The RNA polymerase binds to these promoter regions with the help of other proteins, allowing it to initiate the transcription process at the correct location on the DNA strand.


How does transcription start in the process of gene expression?

Transcription starts in gene expression when the enzyme RNA polymerase binds to the promoter region of a gene on the DNA molecule. This binding signals the start of transcription, where the DNA is used as a template to create a complementary RNA molecule.


What is the function of a consensus sequence in transcription initiation?

Definition:Consensus sequences are the repeated nucleotide's sequence e.g TATA box,GC-rich region etc.Function:And these sequences can be start,stop,promoters' attachment sequences,etc.So they are the cis-acting elements of DNA,with which the trans-acting elements interact.


What makes the beginning of a new gene on DNA in eukaryotes?

The beginning of a new gene on DNA in eukaryotes is marked by the promoter region, which is a specific sequence of nucleotides that initiates the process of transcription by binding to RNA polymerase. This binding signals the start of gene transcription, allowing the RNA polymerase to begin synthesizing a complementary RNA molecule from the DNA template.

What is the role of promoters in transcription control?

Promoters are regions of DNA that provide a binding site for RNA polymerase to initiate transcription. They play a critical role in determining when and how much a particular gene is transcribed. Promoters can be regulated by various factors to control the expression of genes in response to different signals or conditions.


A DNA sequence that signals a gene's start is?

The DNA sequence that signals a gene's start is called a promoter region. This region is crucial for the initiation of transcription, where an enzyme called RNA polymerase binds to the promoter and begins the process of copying the gene into messenger RNA. Promoter regions are typically located near the gene's transcription start site.


What is the key words of transcription?

The key steps of transcription are initiation, elongation, and termination. During initiation, RNA polymerase binds to the promoter region of DNA. Then, during elongation, the RNA polymerase synthesizes an RNA copy of the DNA template. Finally, termination signals the end of transcription and release of the RNA transcript.


Which process stop when rna polymerase comes to a terminator?

Transcription is the process that stops when RNA polymerase is terminated.


Does transcription begin at a promoter region and continue until RNA polymerase reaches a stop codon?

Transcription begins at a promoter region on the DNA where RNA polymerase binds to initiate the process. It continues along the DNA template strand until it reaches a termination signal, not a stop codon, which signals the end of transcription.

What determines where on the DNA molecule transcription begins and ends?

Transcription begins at a specific DNA sequence called the promoter region, which signals the RNA polymerase enzyme where to start transcribing. Transcription ends at a specific DNA sequence called the terminator region, which signals the RNA polymerase to stop transcribing. These regions, along with other regulatory elements, help determine the initiation and termination points of transcription.


What is the terminator in mRNA synthesis?

The terminator in mRNA synthesis is a specific DNA sequence that signals the end of transcription. When the RNA polymerase reaches the terminator sequence, it stops transcribing the mRNA molecule, releasing it from the DNA template.


How does transcription start in the process of gene expression?

Transcription starts in gene expression when the enzyme RNA polymerase binds to the promoter region of a gene on the DNA molecule. This binding signals the start of transcription, where the DNA is used as a template to create a complementary RNA molecule.


What does the promoter do during transcription?

During transcription, the promoter serves as a specific DNA sequence that signals the start site for RNA synthesis. It provides a binding site for RNA polymerase and transcription factors, facilitating the initiation of transcription. Once RNA polymerase binds to the promoter, it unwinds the DNA and begins synthesizing RNA complementary to the DNA template strand. The promoter thus plays a crucial role in regulating gene expression by determining when and how much RNA is produced.


What is a promoter in DNA?

A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.
