Which protein is involved in promoter recognition in eukaryotes?
In eukaryotes, the TATA-binding protein (TBP) is involved in promoter recognition. TBP is a subunit of the transcription factor II D (TFIID) complex, which binds to the TATA box within the promoter region of genes and helps initiate transcription.
Where is the promoter located within a gene?
The promoter is located at the beginning of a gene, before the coding region that specifies the protein or RNA molecule. It is a region of DNA that initiates the process of gene transcription.
What is the function of the 5' UTR promoter in gene expression regulation?
The 5' UTR promoter in gene expression regulation helps to initiate the process of transcription, which is the first step in making a protein from a gene. It signals the start of transcription and helps regulate the amount of protein that is produced from that gene.
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.
What gene specifies a protein that binds to an operatr and physically blocks rna polymerase from binding to a promoter site?
The gene that specifies a protein known as a repressor can bind to the operator region in the DNA, physically blocking RNA polymerase from binding to the promoter site. This mechanism helps regulate gene expression by preventing transcription of the gene.
Which of the statements best describes the promoter of a protein-coding gene?
The promoter is a nontranscribed region of a gene.
Which is the protein involved in promoter recognition in eukaryotes?
TFIID

What describes pieces of DNA to make protein?
A gene is a segment of DNA that codes for a protein.
What best describes the production of RNA translation?
a protein
What is the mechanism by which a protein that binds to an operator inhibits transcription?
When a protein binds to an operator, it blocks the RNA polymerase from binding to the promoter region of the gene. This prevents the transcription process from starting, leading to inhibition of gene expression.
In prokaryotes most of the control of protein synthesis occurs at the level of what?
In prokaryotes, most of the control of protein synthesis occurs at the level of transcription initiation. This is achieved through the regulation of RNA polymerase activity, binding of transcription factors, and modulation of promoter sequences. Ribosomes then translate the mRNA into proteins following transcription.
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.
