Translocation during elongation moves the ribosome along mRNA by:
Show answer and explanation
Correct answer: Three nucleotides at a time
The ribosome moves exactly three nucleotides (one codon) at a time during translocation, powered by GTP hydrolysis of EF-G (EF-2 in eukaryotes). Each shift exposes the next codon at the A site.
