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 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 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
How many bonds does nitrogen have?
1 sigma, 2 pi bonds in a triple bond.
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 is the role of the sigma factor in transcription?
The sigma factor is a protein that helps RNA polymerase bind to the promoter region of a gene during transcription. It plays a crucial role in initiating the process of transcription by guiding RNA polymerase to the correct starting point on the DNA strand.
What does sigma factor assits?
A sigma factor (σ factor) is a protein needed only for initiation of RNA synthesis.

What yitbos stand for?
the meaning of yitbos is a secret protected by the brothers of delta sigma phi... aka, dont worry about it.
What is kappa sigma's initiation?
first, you spend a whole week looking for a 32 year old virgin (male or female). secondly, you bring the virgin to the chapter on the second Tuesday during the initiation month. all current brothers will then proceed to deflower the virgin one by one, and whoever is getting initiated must then take it from the ex-virgin.
When was Sigma Sigma Rho created?
Sigma Sigma Rho was created in 1998.
What sorority was Carrie Underwood in?
