A - Nucleic acids do not changeinto amino acids. Rather, it is the specific sequence of nucleotides in nucleic acids that directstheformationof proteins.
B - Peptides are not bonded to nucleic acids directly. The codons in mRNA are bonded to tRNA molecules, which in turn is bonded to an amino acid.
C - DNA strands are not bonded to amino acids. It is the codons in a strand of mRNA that are bound to tRNA molecules carrying an amino acid.
D - This is correct. The specific sequence of codons in mRNA give rise to a specific sequence of amino acids in the protein formed.
