Is sigma factor a transcription factor
WitrynaAns. Option (4) Heat shock genes. When the concentration of σ38 is the highest of all sigma factors, it directly affects the transcription of specific genes. Sigma factors are proteins that bind to RNA polymerase and help it recognize the promoter DNA sequence for transcription initiation. σ38 is also referred to as the sigma factor for the ... Witryna30 mar 2024 · Comparison with in vitro DNase I protection studies indicates that this protein-DNA interaction is due to non-sequence-specific binding by human mitochondrial transcription factor A (h-mtTFA). Since h-mtTFA can bend and wrap DNA, like its yeast counterpart ABF2, a primary function of h-mtTFA appears to be specific packaging of …
