Problem:
Eukaryotes have three RNA Polymerases that aid in differential regulation of gene expression. Prokaryotes have only one RNA Polymerase;
Question: how do they regulate their gene expression on a broad scale?
A. They don't need to - transcription and translation occur simeltaneously
B. C and D
C. They focus on post-transcriptional regulation by actively degrading mRNA they don't need
D. They have one many different signma factors
E. They have significantly larger promoters for enhanced regulation of gene expression
Please suggest correct answer.
