Shown below are the steps in translation in a scrambled order. Reorder the steps of translation in the correct order (read carefully to determine where to start!): 1. Ribosome moves along mRNA by 3 nucleotides. 2. tRNA enters the A site 3. Release Factor binds in A site and the peptide is released 4. Initiator tRNA enters P site 5. Ribosome binds cap and moves along mRNA to find AUG 6. Peptide bond forms 7. Ribosome encounters a stop codon 5,4,2,6,1,7,3 4,3,5,7,2,6,1 4,1,6,2,3,7,5 5,2,6,4,1,3,7

Place the stages of translation in the correct order. ____ initiator tRNA leaves the ribosome ____ mRNA binds to the small ribosomal subunit ____ new tRNAs continue to bring their corresponding amino acids to the ribosome and the amino acid chain grows ____ peptide bond occurs between amino acids ____ large ribosomal subunit binds and places initiator tRNA into P-site ____ translocation occurs ____ a stop codon is reached and polypeptide breaks free; ribosome subunits separate ____ initiator tRNA binds to the start codon AUG, has anticodon UAC, and is carrying amino acid MET ____ second tRNA enters A-site and has anticodon to complement mRNA codon
Mystique T.
Arrange translation steps in the correct order: 1. Ribosome advances until finding start codon. 2. tRNA carrying Met binds to start codon. 3. mRNA binds to the small ribosomal unit. 4. tRNA carrying corresponding amino acids binds to the mRNA, creating peptide bonds between them. 5. Big ribosomal sub-unit closes system. 6. Ribosome moves to the next codon. 7. Stop codon is reached.
