The DNA sequences that make up the genetic code of an organism determine which traits the organism will exhibit.

How are the instructions coded by DNA translated into an organism's physical traits?
A.
DNA sequences that code for genetic instructions attach to phosphate groups that express an organism's physical traits.
B.
Instructions coded by DNA sequences are translated into nucleotides which express an organism's physical traits.
C.
DNA sequences both code genetic instructions within an organism and express an organism's physical traits.
D.
Instructions coded by DNA sequences are translated into proteins which express an organism's physical traits.

D. Instructions coded by DNA sequences are translated into proteins which express an organism's physical traits.
