Answer 1

D

Step-by-step explanation:

A - Nucleic acids do not change into amino acids. Rather, it is the specific sequence of nucleotides in nucleic acids that directs the formation of 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.
