Question

How many RNA polymerases do eukaryotes have? What about prokaryotes?

Answer 1

Eukaryotes have three RNA polymerases: RNA polymerase I, RNA polymerase II, and RNA polymerase III. Each polymerase is responsible for transcribing different types of RNA, while prokaryotes have a single RNA polymerase that transcribes all types of RNA.

Step-by-step explanation:

Eukaryotes have three RNA polymerases: RNA polymerase I, RNA polymerase II, and RNA polymerase III. Each polymerase is responsible for transcribing different types of RNA. For example, RNA polymerase I transcribes ribosomal RNA (rRNA), RNA polymerase II transcribes messenger RNA (mRNA), and RNA polymerase III transcribes transfer RNA (tRNA) and small nuclear RNA (snRNA).

In contrast, prokaryotes have a single RNA polymerase that transcribes all types of RNA. This single RNA polymerase is structurally distinct from the RNA polymerases found in eukaryotes.
