Explanation / Answer

9. Covalent bonds connect the phosphate of one nucleotide to the sugar of the next to form a single-stranded nucleic acid chain.

Double-stranded DNA is held together using hydrogen-bond between complementary base pairs.

The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide.

9.         In DNA,

           c. the complementary strands of the double helix are held together by weak hydrogen bonds
