Question

Question restatement: Eukaryotic transcription is different than bacterial transcription because eukaryotic transcription ________.

Option 1: occurs in the cytoplasm
- This is incorrect as a general rule for eukaryotes. In eukaryotic cells, transcription occurs in the nucleus, not the cytoplasm. The cytoplasm is where translation occurs, not transcription.

Option 2: only requires one RNA polymerase
- This is inaccurate. Eukaryotes possess multiple RNA polymerases (pol I, pol II, pol III) with distinct roles in transcribing ribosomal RNA, messenger RNA, and transfer RNA. Therefore claiming it requires only one polymerase misrepresents the eukaryotic transcription machinery.

Option 3: requires the uncoiling of the chromatin fiber
- This statement is correct. Eukaryotic DNA is packaged into chromatin, and transcription requires chromatin remodeling to expose DNA. This involves nucleosome repositioning or histone modifications that loosen or uncoil chromatin so transcription machinery can access promoter regions.

Option 4: does not require general transcription factors to initiate transcription
- This is false. Eukaryotic transcription initiation relies on general transcription factors (GTFs) to recruit RNA polymerase II to the promoter and to form the preinitiation complex. Devoid of GTFs would severely impair initiation.

Option 5: does not require the mRNA to be modified
- This is incorrect. Eukaryotic mRNA typically undergoes extensive processing, including 5' capping, splicing, and 3' polyadenylation, before export to the cytoplasm. The statement would mischaracterize post-transcriptional processing that is hallmark of eukaryotic gene expression.

In summary, the statements present several factual points about eukaryotic transcription; the only option aligning with a fundamental difference from bacterial transcription is the chromatin remodeling requirement, while the others describe aspects that are either incorrect or non-unique to the eukaryotic context.
