Question

what type of bond is holding the backbone of DNA strands together?

Answer 1

The strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together. The two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases. @wellerk07

Answer 2

@wellerk07 are there any answers given ?

Answer 3

The sugar-phosphate frame is on the outside, then connected are the deoxyribose, with phosphate groups in between Connected to the deoxyribose are the nucleic acids, and in between the two is a hydrogen bond.
Therefore the weak hydrogen bonds hold the two bases together.

Answer 4

in a nucleotide:
