1. The DNA double helix is held together by two types of bonds, covalent andhydrogen. Covalent bonds occur within each linear strand and strongly bond thebases, sugars, and phosphate groups (both within each component and betweencomponents).Hydrogen bonds occur between the two strands and involve a basefrom one strand with a base from the second in complementary pairing.ovalent bonds occur within each linear strand and strongly bond thebases, sugars, and phosphate groups (both within each component and betweencomponents).

Describe the type of chemical bonding that exists between the atoms in the hydrogen molecule, H2. Covalent bonding. Covalent bonding is the sharing of one or more pairs of electrons between 2 nonmetal atoms, so both. atoms can achieve a Noble Gas electron configuration. When two H atoms bond to form a hydrogen molecule, both. atoms get two electrons, just like a stable helium atom.
