Step-by-step explanation:
Complementarity of bases is the key to the structure of DNA; each strand is formed by the alternation of a sugar and a phosphate group. Attached to each sugar is one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T).
The two strands are held together by hydrogen bonds between complementary bases, that is:
A-T
C-G
