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) so pretty much complementary bases are connected by a hydrogen bonding.
Hydrogen bonds
Hydrogen bonding
order
im pretty sure its covalent bonds and ionic bonds
Ionic bonds, between Na+ and Cl-
Covalent bonds tend to occur between two Non- Metals.
All types of bonds are formed by sharing two electrons between two atoms.
order
Case A - Covalent bonds: Single covalent chemical bonds result from the sharing of a pair of electrons. Double covalent atomic chemical bonds result from the sharing of two pairs of electrons, and triple covalent bonds occur when three pairs of electrons are involved. Case B - Hydrogen bonding and Van-der Wal's Forces.
Ionic bonds are formed between a metal and a nonmetal.

im pretty sure its covalent bonds and ionic bonds
Covalent & Hydrogen
All types of bonds are formed by sharing two electrons between two atoms.
Ionic bonds, between Na+ and Cl-
Both hydrogen and ionic bonds.
Covalent bonds tend to occur between two Non- Metals.
Ammonium ion has two types of bonds. 1. Co-ordianate covalant bonds between H+ and NH3 2. Covalant bonds between nitrogen and hydrogens in ammonia The total number of bonds is 4
electrovalent, covalent and coordinate bonds are the types of bonds.
