Vedclass · Answer

(D) In the $DNA$ double helix structure,the two polynucleotide chains are antiparallel to each other.These two chains are held together by hydrogen bonds between the nitrogenous bases.Specifically,adenine $(A)$ pairs with thymine $(T)$ via two hydrogen bonds,and guanine $(G)$ pairs with cytosine $(C)$ via three hydrogen bonds.Therefore,the correct option is $D$.

In $DNA$,the two polynucleotide chains are held together by which type of bond?
