Prokaryotes:
* RNA Synthesis (Transcription): Happens in the cytoplasm. Prokaryotes lack a nucleus, so their DNA is located in the cytoplasm, where transcription takes place directly.
* Protein Synthesis (Translation): Also occurs in the cytoplasm. Ribosomes, the protein synthesis machinery, are found freely in the cytoplasm.
Eukaryotes:
* RNA Synthesis (Transcription): Occurs in the nucleus. Eukaryotic DNA is enclosed within the nucleus, and transcription happens there.
* Protein Synthesis (Translation): Takes place in the cytoplasm, specifically on ribosomes.
* Free Ribosomes: These are scattered throughout the cytoplasm and make proteins that will function within the cell.
* Bound Ribosomes: These are attached to the endoplasmic reticulum (ER) and make proteins that will be:
* Secreted from the cell
* Used in the membranes of organelles or the cell itself
Key Differences:
* Location: Prokaryotes have a simpler structure, so both processes happen in the cytoplasm. Eukaryotes have a more complex structure, with transcription in the nucleus and translation in the cytoplasm.
* Complexity: The processes of transcription and translation are generally more complex in eukaryotes due to the compartmentalization of the cell.
