What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
Does a promoter determine whether a gene is expressed?
Yes, a promoter is a region of DNA located at the beginning of a gene that initiates the process of transcription, which is the first step in gene expression. The presence of specific sequences in the promoter region can influence the rate and level of gene expression.
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.
Region of DNA that indicates to an enzyme where to bind to make rna?
The region of DNA that indicates where an enzyme should bind to initiate RNA synthesis is called the promoter sequence. The promoter sequence is typically located upstream of the gene that will be transcribed into RNA and is recognized by the enzyme RNA polymerase. Once bound to the promoter, RNA polymerase can begin the process of transcribing the gene into RNA.
What is the functional difference between enhancers and promoter proximal elements?
Enhancers are DNA sequences that can enhance gene expression from a distance, whereas promoter proximal elements are DNA sequences that regulate gene expression in close proximity to the promoter. Enhancers can work in conjunction with promoter proximal elements to fine-tune gene expression levels.

Which of the following statements best describes the promoter of a protein coding gene?
The promoter of a protein-coding gene is a region of DNA located at the beginning of the gene that initiates transcription by providing a binding site for RNA polymerase. It plays a critical role in controlling gene expression by regulating when and how much of the gene is transcribed into mRNA.
Which of the statements best describes the promoter of a protein-coding gene?
The promoter is a nontranscribed region of a gene.

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.
Why does the promoter position differ between prokaryotes and eukaryotes?
In prokaryotes, the promoter is located right before the start codon of the gene, often including the -10 and -35 regions recognized by RNA polymerase. In eukaryotes, the promoter is typically found further upstream of the gene's start site and consists of various sequence elements that interact with transcription factors to initiate gene expression. This difference is due to the dissimilarities in gene regulation mechanisms and the complexity of gene expression in eukaryotic cells compared to prokaryotic cells.

In the control of gene expression in bacteria a regulatory gene a has its own promoter?
The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.
Is DNA junk or not junk?
AnswerThere is junk DNA or non-coding DNA. This DNA is the segment before the promoter of a different gene.
Helps RNA polymerase recognize the start of a gene?
The promoter region in DNA helps RNA polymerase recognize the start of a gene. The promoter contains specific sequences that serve as binding sites for RNA polymerase, allowing it to initiate transcription of the gene. Transcription factors also play a role in assisting RNA polymerase in recognizing and binding to the promoter region.
Does eukaryotic transcription begin before the promoter clearance?
No, in eukaryotic transcription, promoter clearance must occur before transcription can begin. This process involves the recruitment of transcription factors and RNA polymerase to the promoter region, followed by their verification by elongation complex formation, allowing transcription to initiate.
