Detailed explanation-1: -So, the correct option is ‘The sequence of codons in mRNA’.
Detailed explanation-2: -The sequence of amino acids determines each protein’s unique 3-dimensional structure and its specific function.
Detailed explanation-3: -Sequence, structure and function The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function. This is why mutations that alter amino acid sequence can affect the function of a protein.
Detailed explanation-4: -Proteins are chains of amino acids that assemble via amide bonds known as peptide linkages. The difference in the side-chain group or R-group is what determines the unique properties of each amino acid.
