How do eukaryotic and prokaryotic RNA polymerases compare?
A) Since eukaryotic RNA polymerases are more complex, little homology has been found between the actual protein sequences in the catalytic subunits.
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.
