The correct answer is the type and sequence of molecules along each strand.
The DNA is formed of molecules known as nucleotides. Each nucleotide comprises a sugar group, a phosphate group, and a nitrogenous base. The four kinds of nitrogen bases are thymine (T), adenine (A), cytosine (C), and uracil (U). The order of these bases is what that determines the genetic code or the DNA instructions.
