Detailed explanation-1: -Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
Detailed explanation-2: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-3: -Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Detailed explanation-4: -The role of the hydrogen bonds, which have sometimes been seen as crucial to holding DNA helixes together, appears to be more to do with sorting the base pairs, so that they link together in the correct sequence. The discovery is crucial for understanding DNA’s relationship with its environment.
