Question

Compare and contrast prokaryotic and eukaryotic transcription.

A. Prokaryotic transcription occurs in the cytoplasm, while eukaryotic transcription occurs in the nucleus.
B. Prokaryotic transcription uses a single RNA polymerase, while eukaryotic transcription uses three different RNA polymerases.
C. Prokaryotic and eukaryotic transcription both require the presence of transcription factors.
D. Prokaryotic and eukaryotic transcription both produce RNA transcripts that are identical to the DNA template.

Answer 1

Prokaryotic transcription occurs in the cytoplasm using a single RNA polymerase, while eukaryotic transcription occurs in the nucleus using three different RNA polymerases. Prokaryotic transcription does not require transcription factors, while eukaryotic transcription does. The RNA transcripts produced in prokaryotes and eukaryotes differ in processing before translation.

Step-by-step explanation:

Prokaryotic transcription: Occurs in the cytoplasm. It uses a single RNA polymerase. It does not require the presence of transcription factors. The RNA transcripts are identical to the DNA template.

Eukaryotic transcription: Occurs in the nucleus. It uses three different RNA polymerases. It requires the presence of transcription factors. The RNA transcripts undergo processing before they are ready to be translated.
