Solution:

Two strands of DNA molecules are held together by hydrogen bonds between their bases. Adenine (A), a purine of one chain lies exactly opposite thymine (T), a pyrimidine of the other chain. Similarly, Cytosine (C), a pyrimidine lies opposite guanine (G) a purine. Thus the complementary strand would be 5' - ATG CGC TGC - 3'.
