Which part of a dna molecule carries the genetic instructions that are unique for each individual; the sugar-phosphate backbone or the nitrogen-containing bases?

the sugar phosphate backbone

Explanation:

just took test

      The right answer to this question is: the nitrogen-containing bases.

Explanation:

      These nitrogen bases are called nucleic acids (DNA), and they're divided into four of them on a DNA ribbon, these nitrogen-containing bases are: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). They combine themselves in a way that this will create a specific protein for each function of the body, and this will give the body its whole genetic fenotype.
