Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.

What type of chemical bone holds together the base pairs?
The backbone of a DNA molecule is composed of 1:1 molecular phosphoric acid and deoxyribose, together with the base (A, T, C, or G) is called a nucleotide. While the backbone of a RNA molecule is composed of 1:1 molecular phosphoric acid and ribose.
What type of bond holds the two sides of the DNA molecule together?
DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G). A and T are connected by two hydrogen bonds. G and C are connected by three hydrogen bonds.
Which type of chemical bonding holds the two strands of DNA together in the double helix?
When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand. This means as the two strands are split apart, a new complimentary strand is formed against each, resulting in two identical double helices where there was just one before. It is by this means that the instructions for the code of life are copied and passed on.
