How Do Eukaryotic and Prokaryotic RNA Polymerases Compare

question 37

Multiple Choice

How do eukaryotic and prokaryotic RNA polymerases compare?

• B) Since eukaryotic transcription is less complex than in prokaryotes, monomeric RNA polymerases are used.
• C) Despite their added complexity, eukaryotic and prokaryotic RNA polymerases are generally homologous.
• D) Eukaryotic and prokaryotic RNA polymerases are virtually identical.
