Compare the types and functions of RNA polymerases in prokaryotes and eukaryotes.
Understand the Problem
The question is asking for a comparison between the different types of RNA polymerases and their specific functions in prokaryotic and eukaryotic organisms. This involves discussing the structural differences, the roles they play in gene expression and transcription processes in both cellular types.
Answer
Prokaryotes have one RNA polymerase; eukaryotes have three types.
Prokaryotes have a single type of RNA polymerase for synthesizing all RNA types, while eukaryotes have multiple types: RNA Polymerase I, II, and III for different RNA functions.
Answer for screen readers
Prokaryotes have a single type of RNA polymerase for synthesizing all RNA types, while eukaryotes have multiple types: RNA Polymerase I, II, and III for different RNA functions.
More Information
In eukaryotes, RNA Polymerase I is responsible for ribosomal RNA (rRNA) synthesis, Polymerase II for messenger RNA (mRNA) and small nuclear RNA (snRNA), and Polymerase III for transfer RNA (tRNA) and other small RNAs. Prokaryotic RNA polymerase synthesizes all these types with different sigma factors aiding specificity.
Tips
A common mistake is forgetting the specificity of each eukaryotic RNA polymerase and oversimplifying their roles. It is also essential to remember the involvement of sigma factors in prokaryotic transcription.
