I found the exercise on the internet and attached is the image of the DNA strand mentioned in the question.
Between each Thymine - Adenine bond there are two hydrogen bonds, while in each Guanine - Cytosine bond there are three hydrogen bonds. This is important because allows each base to connect only with that that is the correspondent.
So, the number <span>hydrogen bonds that exist between DNAs dna strand and its complementary strand is 19.
2bonds</span>×2 (1 Adenine + 1 Thymine) + 3bonds×5 (2 guanines + 3 cytosines) = 19 bonds
