Internal and external hydrogen bonds stabilize the DNA molecule. The two strands of DNA stay together by H bonds that occur between complementary nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base pairs, and between the cytosine and the guanine there are three.
Best Answer: Dna is a double helical structure with two strands of nitrogenous bases being held together by hydrogen bonds. Phosphodiester bonds hold bases together on the same strand.Between deoxyribose and a phosphate group. Hydrogen bonds hold the two strands together. Adenine and Thymine have 2 H bonds always.Guanine and Cytosine have 3 H bonds always.hosphodiester bonds hold bases together on the same strand. Between deoxyribose and a phosphate group. Hydrogen bonds hold the two strands together. Adenine and Thymine have 2 H bonds always.
