Question

Quizplus · Accepted Answer

Nucleotides are joined together in a single strand of DNA by phosphodiester bonds, which form between the phosphate group on one nucleotide and the sugar group on the adjacent nucleotide. This results in a sugar-phosphate backbone that runs along the length of the DNA strand.
