Study Notes
Eukaryotic Gene Expression
- In eukaryotes, transcription and translation are uncoupled, allowing for more complex gene regulation and greater control over protein synthesis.
Eukaryotic Messenger RNA Processing
- One process that is NOT a part of eukaryotic messenger RNA (mRNA) processing is translation, as it occurs in the cytoplasm.
- Eukaryotic mRNA is characterized by the presence of a 5' cap and a 3' poly-A tail.
RNA Polymerases in Eukaryotes
- There are three RNA polymerases in eukaryotes: RNA polymerase I, RNA polymerase II, and RNA polymerase III.
- RNA polymerase II is responsible for transcribing all the protein-coding genes in eukaryotes.
