Here Is your answer....

s0,Thé Answer Is.. :

Base pairs between anti-parallelcomplementary DNA strands arejoined by hydrogen bonds to form a double helix structure. Adenine and thymine are joined by 2 hydrogenbonds, and cytosine and guanine arejoined by 3 hydrogen bonds. The hydrophobic nitrogenous bases are located internally within the double helix..
