How do nucleotides and hydrogen bonds affect the structure of dna?

This is the structure of DNA and nucleotide is the phosphate group with sugar (the pink one ) and base that are 4 different bases : A, T, C, G and between these bases we have hydrogen bonds  and you can see that always it like : C≡G
A=T :))) i hope that helps :)))https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwiawYOO7-...
