TRANSLATION
• Translation is the process of protein synthesis.
• The information encoded in the mRNA is translated
into amino acid sequence through the joint activity of
the tRNAs and ribosomes.
STAGES OF TRANSLATION
• INITIATION
• ELONGATION
• TERMINATION
TRANSLATION REQUIRES:
• Ribosomes
• Amino Acids
• Messenger RNA (mRNA)
• Transfer RNA (tRNA)
• Enzymes
(Aminoacyl synthetase, Aminoacyl peptidase)
• ATP
FACTORS FOR TRANSLTION
1. Initiation factor
2. Elongation factor
3. Releasing factor
DIFFERENCE B/W PRO & EUKARYOTIC
TRANSLATION
PROKARYOTIC CELL
• 30S and 50S =70S Ribosomes
• Occur in the cytoplasm
• Starting with N-formyl
methionine
• Unstable – live for few seconds
to 2 mins
• Faster process
EUKARYOTIC CELL
• 40S and 60S =80S Ribosomes
• Occur in the nucleus
• Starting with methionine
• Stable – live for few hours to
days
• Slower process
