In the process of translation, 'Translocation' refers to:

  1. The movement of mature mRNA from the nucleus to the cytoplasm
  2. The movement of the ribosome one codon forward along the mRNA
  3. The transport of amino acids into the plant vacuole
  4. The shifting of electrons in the chlorophyll molecule
Show answer and explanation

Correct answer: The movement of the ribosome one codon forward along the mRNA

Translocation occurs during the elongation phase, where the ribosome moves three nucleotides toward the 3' end of the mRNA. This process is powered by GTP hydrolysis and facilitated by Elongation Factor G (EF-G).
