SIMILARITIES:
- Both prokaryotic and eukaryotic translation processes use mRNA as a template.
DIFFERENCES:
PROKARYOTIC TRANSLATION:
- Prokaryotic transcription and translation are simultaneous processes.
- Prokaryotic translation occurs in 70S ribosomes in the cytoplasm.
- Prokaryotic translation is a faster process (adds 20 amino acids/second)
- Shine-Dalgarno sequence is found in the 5′ UTR, located 8-10 nucleotides upstream to the start codon.
- Cap- independent initiation.
EUKARYOTIC TRANSLATION:
- Eukaryotic transcription and translation are discontinuous processes.
- Eukaryotic translation performed by the 80S ribosomes attached with the ER.
- Eukaryotic translation is a slower process (adds a single amino acid /second)
- Kozak sequence is found in the 5′ UTR, a few nucleotides upstream to the start codon.
- Both cap-dependent and cap-independent initiation.
