Elongation Factors Translocate the Ribosome in the 3' Direction by a Distance

Question

Elongation factors translocate the ribosome in the 3' direction by a distance of______ .
A) one nucleotide
B) two nucleotides
C) two codons
D) one codon
E) three codons

Accepted Answer

Elongation factors translocate the ribosome in the 3' direction by a distance of one codon, which is equivalent to three nucleotides. This is essential for the ribosome to read the mRNA and add the correct amino acids to the growing polypeptide chain.
