<u>Answer</u>: B. complex, folded chains of amino acid
Proteins are a class of large organic compounds composed of amino acids in the form of one or more long chains. The amino acid sequence determines the protein's shape and is in turn dictated by the DNA sequence that codes it. Proteins are vital for all the body's functions.
Once they understood the structure of DNA a lot of things became more clear including how DNA was replicated.
So I think your answer is copies? meaning how it is copied (replicated).
The structure also led later on to how it was transcribed into mRNA (and eventually into proteins by ribosomes).
