The nucleotides in the backbone of DNA are held together by
A)hydrogen bonds.
B)ionic bonds.
C)phosphodiester linkages.
D)peptide bonds.

Question

Quizplus · Accepted Answer

The nucleotides in the backbone of DNA are covalently linked by phosphodiester linkages between the 5' carbon of one nucleotide and the 3' carbon of the adjacent nucleotide. This forms a sugar-phosphate backbone that provides stability to the DNA molecule.
