What is Definition of noise factor in six sigma?
Six Sigma is the basis on top.
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 attachment site for RNA polymerase?
according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA. The factor 'sigma' will only attach itself to the complex DNA / RNA polymerase when the RNA polymerase is attached to a promoter. Another hypothesis is that the factor sigma attaches to RNApol anyway and the enzyme is then able to slide along the DNA until it finds a promoter. It prevents detaching and speeds up promoter location, and decreases the affinity of RNApol for general regions of DNA. " Therefore, the answer seems to be, RNA attaches to DNA through a small protein called the factor sigma once the RNA polymerase attaches itself to a chain sequence called a "promoter". according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA.

Actually there are many promoter and many genes but which gene to be transcribed is decided by sigma factor.
