Question

what happens at the end of translation?
a. the ribosome locates the start codon.
b. two amino acids form a peptide bond.
c. trna molecules attach to codons.
d. the amino acids detach from the ribosome.

Explanation:

Translation is the process of protein - synthesis in which a sequence of mRNA is used to assemble amino acids into a polypeptide chain. At the start of translation, the ribosome locates the start codon (A is incorrect). During translation, tRNA molecules attach to codons and two amino acids form peptide bonds (B and C are processes during translation). At the end of translation, the completed polypeptide (amino - acid chain) detaches from the ribosome.

Answer:

D. The amino acids detach from the ribosome
