Question

Which of the following examples of how the process of eukaryotic transcription differs from the process of bacterial transcription is/are true? Select all that apply.

1.Bacterial RNA polymerase can initiate transcription without the help of additional proteins, whereas eukaryotic RNA polymerases need general transcription factors.

2.Eukaryotic transcription is affected by chromatin structure and nucleosomes, whereas bacteria lack nucleosomes.

3.Bacterial cells contain a single RNA polymerase, whereas eukaryotic cells have three.

4.In eukaryotic cells, transcription regulators can influence transcriptional initiation thousands of nucleotides away from the promoter, whereas bacterial regulatory sequences are very close to the promoter.

Explanation / Answer

1.Bacterial RNA polymerase can initiate transcription without the help of additional proteins, whereas eukaryotic RNA polymerases need general transcription factors.
