RNA Polymerase Recruitment in Prokaryotes

What is RNA polymerase recruitment in prokaryotes?

• Binding of RNA polymerase to the terminator region of a gene

• Recruitment of RNA polymerase to the promoter region of a gene

• Activation of RNA polymerase by transcription factors

• Inhibition of RNA polymerase activity in prokaryotes

Which protein is responsible for recruiting RNA polymerase to the promoter region in prokaryotes?

• RNA polymerase II

• transcription factor

• ribosome

• sigma factor

What is the role of sigma factor in RNA polymerase recruitment?

• The sigma factor stabilizes the RNA polymerase complex.

• The sigma factor enhances the speed of transcription.

• The sigma factor prevents RNA polymerase from binding to the promoter region.

• The sigma factor recognizes the promoter region and guides RNA polymerase to initiate transcription.

How does the sigma factor recognize the promoter region?

• Through interaction with enhancer elements

• Through binding to RNA polymerase

• Through recognition of introns

• Through specific DNA sequences called promoter elements

What are the different steps involved in RNA polymerase recruitment in prokaryotes?

• Recognition of enhancer region, unwinding of DNA, RNA synthesis, release of sigma factor, dissociation of RNA polymerase and RNA molecule from DNA

• Recognition of terminator region, unwinding of DNA, RNA synthesis, release of sigma factor, dissociation of RNA polymerase and RNA molecule from DNA

• Recognition of operator region, unwinding of DNA, RNA synthesis, release of sigma factor, dissociation of RNA polymerase and RNA molecule from DNA

• Recognition of promoter region, unwinding of DNA, RNA synthesis, release of sigma factor, dissociation of RNA polymerase and RNA molecule from DNA

What is the significance of RNA polymerase recruitment in prokaryotes?

• RNA polymerase recruitment in prokaryotes is significant because it allows for the initiation of transcription.

• RNA polymerase recruitment in prokaryotes is significant for protein synthesis.

• RNA polymerase recruitment in prokaryotes is not significant.

• RNA polymerase recruitment in prokaryotes is only significant for DNA replication.

How is RNA polymerase recruitment regulated in prokaryotes?

• RNA polymerase recruitment in prokaryotes is regulated through transcription factors, promoter sequences, and regulatory proteins.

• RNA polymerase recruitment in prokaryotes is regulated through DNA replication.

• RNA polymerase recruitment in prokaryotes is regulated by ribosomes.

• RNA polymerase recruitment in prokaryotes is regulated by the Golgi apparatus.

What are the factors that can affect RNA polymerase recruitment in prokaryotes?

• chromatin structure, DNA sequence motifs, RNA polymerase concentration, and ribosome availability

• transcription factors, RNA polymerase concentration, DNA methylation, and histone modification

• transcription factors, DNA sequence motifs, chromatin structure, and regulatory proteins

• temperature, pH level, RNA polymerase concentration, and ribosome availability

What happens if RNA polymerase recruitment is impaired in prokaryotes?

• Protein synthesis cannot occur.

• DNA replication cannot occur.

• Transcription of genes cannot occur.

• Translation of genes cannot occur.

What are the similarities and differences in RNA polymerase recruitment between prokaryotes and eukaryotes?

• The recruitment process in prokaryotes is simpler and involves direct binding of RNA polymerase to the promoter region, while in eukaryotes, RNA polymerase II is recruited by transcription factors.

• In prokaryotes, RNA polymerase II is recruited by transcription factors, while in eukaryotes, it directly binds to the promoter region.

• The recruitment process is the same in both prokaryotes and eukaryotes, involving direct binding of RNA polymerase to the promoter region.

• In prokaryotes, RNA polymerase is recruited by transcription factors, while in eukaryotes, it directly binds to the promoter region.
