Differbetween
The main difference between prokaryotic and eukaryotic translation is that prokaryotic translation is a simultaneous process with transcription whereas eukaryotic translation is a separate process from its transcription.

How does prokaryotic translation differ from eukaryotic translation?
Eukaryotic and Prokaryotic translations are involved in protein synthesis. The key difference between eukaryotic and prokaryotic translation is that eukaryotic translation and transcription is an asynchronous process whereas prokaryotic translation and transcription is a synchronous process.
What is the difference between prokaryotic and eukaryotic cells in transcription and translation?
In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm. In prokaryotes, the two processes are closely coupled (Figure 28.15).
What is the major difference in the termination stage of translation between prokaryotes and eukaryotes?
Translation has three main stages: initiation, elongation, and termination. These differ slightly in prokaryotic and eukaryotic organisms: in prokaryotes, translation occurs in the cytoplasm, while in eukaryotes, translation takes place in the endoplasmic reticulum.
What are the key differences between prokaryotic and eukaryotic protein synthesis?
9 Differences Between Eukaryotic and Prokaryotic Protein Synthesis
| Prokaryotes | Eukaryotes (Cytoplasm) |
|---|---|
| No cap on mRNA | 5′ end of mRNA is recognized by cap |
| Start codon is next AUG after ribosome-binding site | No ribosome-binding site so first AUG in mRNA is used |
| First amino acid is formyl-Met | First Met is unmodified |
What are 3 steps of translation?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.
How does translation start in eukaryotes?
Eukaryotic translation initiation: Complex of small ribosomal subnit and initiator tRNA (bearing methionine) binds to 5' cap of mRNA. ... Initiator tRNA binds to start codon. Large ribosomal subunit comes together with the mRNA, initiator tRNA, and small ribosomal subunit to form the initiation complex.
What are 4 differences between prokaryotic and eukaryotic cells?
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. ... Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
What are the major differences between transcription of prokaryotes and eukaryotes?
Prokaryotic vs Eukaryotic Transcription
| Prokaryotic Transcription | Eukaryotic Transcription |
|---|---|
| RNAs are released and processed in the cytoplasm | RNAs are released and processed in the nucleus |
| RNA polymerases are a complex of five polypeptides. | RNA polymerases are a complex of 10 -15 polypeptides. |
Is transcription the same in prokaryotes and eukaryotes?
Both prokaryotes and eukaryotes perform fundamentally the same process of transcription, with the important difference of the membrane-bound nucleus in eukaryotes. With the genes bound in the nucleus, transcription occurs in the nucleus of the cell and the mRNA transcript must be transported to the cytoplasm.
How is translation terminated in prokaryotes?
Termination of translation occurs when a nonsense codon (UAA, UAG, or UGA) is encountered. Upon aligning with the A site, these nonsense codons are recognized by protein release factors that resemble tRNAs.
Why are Polysomes not found in eukaryotes?
Multiple ribosomes move along the coding region of mRNA, creating a polysome. The ability of multiple ribosomes to function on an mRNA molecule explains the limited abundance of mRNA in the cell. Polyribosome structure differs between prokaryotic polysomes, eukaryotic polysomes, and membrane bound polysomes.
Why is prokaryotic translation faster?
Why is translation so much faster in prokaryotes than eukaryotes? The prokaryotic cells have a much smaller genome and their translation happen simultaneously with their transcription (because they both take place in the cytosol). They also have a operon system, whereas in eukaryotes every gene has its own promoter.
