What role does the sigma factor play in gene transcription?
The sigma factor is a protein that helps RNA polymerase bind to specific DNA sequences, known as promoters, to initiate gene transcription. It plays a crucial role in determining which genes are transcribed and when they are transcribed in a cell.
What role does the sigma factor of RNA polymerase play in transcription?
The sigma factor of RNA polymerase helps to recognize and bind to specific DNA sequences, known as promoters, to initiate the process of transcription. It plays a crucial role in determining which genes are transcribed and when they are transcribed in a cell.
What is the function of sigma factor in transcription?
when RNA Polymerase meet the correct promoter(TATA box), it will bind at that region and then sigma factor will also bind to the RNA Polymerase.once ATP give energy, sigma factor will dissoiates from RNA Polymerase and the enzyme start to unwind the double helix
What is the difference between sigma factors and transcription factors in gene regulation?
Sigma factors are specific proteins in prokaryotes that help RNA polymerase bind to the promoter region of a gene to initiate transcription. Transcription factors, on the other hand, are proteins in eukaryotes that regulate gene expression by binding to specific DNA sequences and influencing the activity of RNA polymerase. In summary, sigma factors are specific to prokaryotes and help initiate transcription, while transcription factors are found in eukaryotes and regulate gene expression.
What role do sigma factors play in gene regulation and transcriptional initiation?
Sigma factors are proteins that help RNA polymerase bind to specific DNA sequences, allowing for the initiation of transcription. They play a crucial role in gene regulation by determining which genes are transcribed and when, thus controlling the expression of various proteins in the cell.

What is the main function of transcription factor A in the process of transcription?
Transcription factor A binds to specific DNA sequences called promoter regions to initiate the transcription of a gene. It helps RNA polymerase recognize the promoter and start transcribing the gene into mRNA. Transcription factor A plays a crucial role in regulating gene expression by controlling when and how much mRNA is produced.
What does sigma factor assits?
A sigma factor (σ factor) is a protein needed only for initiation of RNA synthesis.

What is a transcription factor?
regulatory proteins
Full form of tga transcription factor?
Referring to the TGA1 article in Plant Cell in 1992 by Schindler et al., TGA is an abbreviation for the DNA motif to which TGA1 binds. The authors show that TGA1 binds preferentially to TGACG motifs. Thus the full name should be TGACG motif binding (TGA) transcription factors. Mark Z.
What is the role of the transactivation domain?
Transactivation domains are regions on a transcription factor (protein) which helps to activate transcription by contacting transcription factor. This is believed to be done to recruit the general transcription factors onto the gene promoter region.
Is RNA polymerase considered a transcription factor?
No, RNA polymerase is not considered a transcription factor. RNA polymerase is an enzyme responsible for catalyzing the synthesis of RNA from a DNA template during the process of transcription. Transcription factors are proteins that regulate the transcription of specific genes by binding to DNA sequences.
What is Definition of noise factor in six sigma?
