Explanation:
Detailed explanation-1: -Hydrogen bond (H-bond) binds the nitrogen bases between the two strands of DNA. There are two H-bonds between A and T; three H-bonds between G and C.
Detailed explanation-2: -hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components).
Detailed explanation-3: -Nitrogenous bases in nucleic acids are held together by hydrogen bonds. Hydrogen bonds occur when hydrogen is covalently bonded to a much more electronegative element such as chlorine or nitrogen.
