Place the steps of translation in the correct order.

  1. Ribosomes starts reading the code

  2. Translation stops when the ribosomes reaches the stop codon

  3. A tRNA carrying an amino acid binds to its anticodon to the codon on mRNA

  4. Bonds form between amino acids and the polypeptide chain grows

  5. Ribosome attaches to mRNA
