Explanation:
Detailed explanation-1: -After reading our mRNA transcript and using the table provided, we have now determined the correct sequence of amino acids. Reading from the five prime to three prime direction, the sequence the codons will be translated into is methionine, valine, histidine, leucine.
Detailed explanation-2: -a The genetic code contains four codons for proline: CCG, CCC, CCU, and CCA.
