What must occur for protien translation to begin? A. A water molecule must be added to the protien chain. B. A peptide bond must form between subnits of mRNA. C. The amino acid Cys must be picked up by tRNA. D. The codon AUG must be identified

A peptide bond must form between subunits of mRNA

Explanation:

For translation to occur,A peptide bond must form between subunits of mRNA because it is through the formation of peptide bond between subunits of mRNA that the small ribosomal subunit binds to the start of the mRNA sequence

chemical because it warmed up which involves temperature and it bubbled which includes changing
