If the complementarity between DNA strands could no longer occur, the DNA would become single stranded. This is because one of the key features of DNA is the pairing of complementary bases (A with T, and C with G) between the two strands. If this pairing is disrupted, the two strands will separate and the DNA will become single stranded.
