Answer:
Traits are coded for in DNA, specifically in genes.
Explanation:
DNA, as you probably already know, is made up of long sequences of nucleotides of A's, T's, C's, and G's. When transcripted into mRNA and translated into proteins in ribosomes, the order of these nucleotides signal which amino acids to produce for the protein. Proteins are extremely important and have many roles throughout the body, which means they actualize the code of DNA into physical traits. I hope this helped.
