Detailed explanation-1: -Hydrogen bond (H-bond) binds the nitrogen bases between the two strands of DNA.
Detailed explanation-2: -The two nitrogenous bases that make up a complementary base pair are attached together with a weak chemical connection: a hydrogen bond.
Detailed explanation-3: -Hydrogen bonds are the weakest bonds we study in this course.
Detailed explanation-4: -DNA can contain four types of nitrogenous base: adenine, guanine, cytosine, and thymine. Each strand is linked to the other strand by complementary pairs of organic bases. Cytosine always pairs with guanine, and adenine always pairs with thymine. The complementary base pairs are held together by weak hydrogen bonds.
Detailed explanation-5: -For instance, strong covalent bonds hold together the chemical building blocks that make up a strand of DNA. However, weaker hydrogen bonds hold together the two strands of the DNA double helix.
