Which of the following statements about eukaryotic and prokaryotic RNA polymerases, is false ?
A) There are 3 different RNA polymerases in eukaryotes, instead of just one.
B) Eukaryotic polymerases have the same number of subunits as prokaryotic ones.
C) Only prokaryotic polymerases use sigma factor.
D) The enzymatic mechanism is the same for both types of organisms.

Question

Quizplus · Accepted Answer

Eukaryotic RNA polymerases have more subunits than prokaryotic RNA polymerases. Eukaryotes have RNA polymerase I, II, and III, each composed of multiple subunits, whereas prokaryotic RNA polymerase typically consists of fewer subunits and operates with the help of a sigma factor for initiation.
