Eukaryotic and Bacterial RNA Polymerases are Different Such That

Question

Eukaryotic and bacterial RNA polymerases are different such that:
A)eukaryotes have several types of RNA polymerases,whereas bacteria only have one.
B)unlike bacterial RNA polymerase,eukaryotic RNA pol II can synthesize mRNA and also coordinate mRNA processing.
C)eukaryotic RNA polymerases are multimeric,whereas bacterial RNA polymerase is not.
D)eukaryotes have several types of RNA polymerases,one of which can synthesize mRNA and also coordinate mRNA processing,whereas bacteria only have one type of RNA polymerase that does not coordinate mRNA processing.
E)eukaryotes have several types of multimeric RNA polymerases,whereas bacteria only have one monomeric RNA polymerase.

Accepted Answer

Eukaryotes have multiple types of RNA polymerases, and one of them (RNA Pol II) can synthesize mRNA and coordinate mRNA processing (such as capping and splicing). Bacteria only have one type of RNA polymerase, which does not perform these functions. Also, while eukaryotic RNA polymerases are multimeric, bacterial RNA polymerase is not. Therefore, option D is the most accurate choice.
