nitrogenous bases on the outside

a single nucleotide strand twisted in a spiral

two nucleotide strands wound in a double helix

D.) Two nucleotide strands wound in a double helix.

Their model shows that DNA is composed of two double strand of nucleotide which are twisted around each other and run in antiparallel direction. the phosphate group and pentose sugar are present on outside, while nitrogenous base is present on inside
