Question

Write the number of RNA polymerases involved in the transcription of DNA in a prokaryote and eukaryotes.

Hint:

In prokaryotes, a single RNA polymerase performs all RNA synthesis, whereas eukaryotes use three specialized polymerases for different types of RNA.

Answer 1

- Prokaryotes have a single RNA polymerase. - Eukaryotes have three RNA polymerases: RNA polymerase I, II, and III. - Prokaryotes rely on a single RNA polymerase for synthesizing all types of RNA (mRNA, tRNA, and rRNA). - Eukaryotes have specialized RNA polymerases: - RNA polymerase I synthesizes rRNA. - RNA polymerase II synthesizes mRNA. - RNA polymerase III synthesizes tRNA and some small RNAs. }
