hydrogen bonds
the bases are paired by hydrogen bounds
The chemical bond that holds together the complementary nucleotide bases in DNA is called a hydrogen bond. These bonds form between specific pairs of bases (A-T and G-C) and help stabilize the double helix structure of the DNA molecule.
there is no bone in DNA but what holds the complementary base pairs are the following: two hydrogen bonds between adenine and thymine, and three hydrogen bonds between guanine and cytosine. i hoped this helped :)
your teacher will probably accept hydrogen bonds, however it is more of an attraction not a physical bond

Nitrogenous bases in DNA bond together through hydrogen bonds. Adenine pairs with thymine and guanine pairs with cytosine, forming stable base pairs within the DNA double helix.
The two halves of a DNA double helix are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine and guanine pairs with cytosine. This base pairing allows for the specificity and stability of the DNA molecule.
Hydrogen bonds hold bases together in DNA. These bonds form between the nitrogenous bases adenine (A) and thymine (T), and between cytosine (C) and guanine (G), helping to stabilize the DNA molecule's double helix structure.
A phosphodiester bond holds the deoxyribose sugar and phosphate group together in a DNA molecule. This bond forms between the 3' carbon of one deoxyribose and the 5' carbon of the adjacent deoxyribose in the DNA backbone.
Hydrogen bonds do this.
Hydrogen bonds hold together the two strands of DNA. These bonds form between specific base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C), creating the double helix structure of DNA.
