What type of linkages hold together monomers of DNA?

Answer»

SOLUTION :The DNA DOUBLE helix or duplex is held together by two forces
(i) Hydrogen bonding between COMPLEMENTARY BASE pairs
(II) Base-stacking interactions.The complementary between the DNA strands is attributable to the hydrogen bonding between base pairs but the base stacking interactions are largely non-specific, make the major contribution to the stability of the double helix
