Answer:
a. eukaryotes have three different RNA polymerases, whereas prokaryotes only have one RNA polymerase
Explanation:
The initiation represents the beginning of RNA production. Initially, RNA polymerase (transcription catalyzing enzyme) recognizes in DNA the so-called promoter regions. In prokaryotes, there is only one type of RNA polymerase; In eukaryotes, three RNA polymerases are described, and thus the transcription process in this group is more complex.
In the initiation step, we also observe the opening of the DNA strand, a process known as unfolding. This opening occurs because of the rupture between the connections that arise between the bases.
