Which of the Following is Most Involved in Elongation of the RNA

Question

Which of the following is most involved in elongation of the RNA transcript?
A)sigma factor
B)UP elements
C)-10 region
D)both sigma factor and UP elements

Accepted Answer

Sigma factor is primarily involved in the initiation phase of transcription in bacteria, helping the RNA polymerase to bind to the promoter. However, the question asks about elongation, and none of the options directly relate to the elongation phase of RNA transcription. Therefore, it seems there might be a misunderstanding in the question or options provided. Typically, the RNA polymerase core enzyme is responsible for the elongation of the RNA transcript after the sigma factor has facilitated the initiation phase.
