E. coli cells achieve a great deal of gene regulatory expression through the $\sigma$subunit of RNA polymerase. Which $\sigma$ subunit is present most often since it promotes the production of most of the proteins required under normal conditions within the cell? A) $\sigma$^N B) $\sigma$^S C) $\sigma$^H D) $\sigma$³⁰ E) $\sigma$⁷⁰

Question

The question seems to be incorrectly formatted with symbols and numbers that don't correspond to known subunits of RNA polymerase in E. coli. However, the correct answer choice is likely intended to refer to the sigma factor (σ) that is most commonly associated with the RNA polymerase in E. coli under normal conditions, which is σ^70 (sigma 70). This is the primary sigma factor used during exponential growth to recognize the promoters of genes required for most basic functions.
