When nucleotides join together, their sugar and phosphate sections form long strands. A single DNA molecule is made of two strands of nucleotides. This forms the "backbone" two DNA strands of a DNA molecule. The bases on each nucleotide face inward, sugar toward each other. base; A, C, G or T phosphate This allows bases on opposite strands to interact, keeping the two strands together.
