Translation

• 1. Ribosome attaches to mRNA (first and second codon is in ribosome)
• 2. First codon is start codon and attracts a complementary tRNA molecule (carrying a complementary amino acid)
• 3. second tRNA attaches to second codon
• 4. peptide bond forms between the two amino acids
• 5. Ribosome moves by 1 codon
• 6. first tRNA leaves codon and a third tRNA moves to third codon
• 7. peptide bond forms between second and third amino acid
• 8. ribosome continues to move along mRNA until it reaches a stop codon
• 9. ribosome detaches and a polypeptide is released folding into correct shape
