The weak chemical bonds important in holding the DNA double helix together is the: ionic bond polar covalent nonpolar covalent hydrogen bond

Strands of DNA are joined byMultiple Choicehydrogen bonds.covalent bonds.ionic bonds.phosphodiester bonds.

The reason for double helical structure of DNA is the operation of :Van der Waals forcesElectrostatic attractionsHydrogen bondingDipole - Dipole interactions

The strands of the DNA double helix are held together by _______________________________________.

What is the structure of the DNA double helix

The double helix structure of DNA is like a twisted ladder that is held together by the "rungs". Each rung consists of:a single basea pair of bases linked togethera proteina pair of atoms linked together
