Transcription in Bacteria Differs from Transcription in a Eukaryotic Cell

question 27

Multiple Choice

Transcription in bacteria differs from transcription in a eukaryotic cell because

• B)RNA polymerase (along with its sigma subunit) requires the general transcription factors to assemble at the promoter before polymerase can begin transcription.
• C)the sigma subunit must associate with the appropriate type of RNA polymerase to produce mRNAs.
• D)RNA polymerase must be phosphorylated at its C-terminal tail for transcription to proceed.
