Why is it important that the nitrogenous bases break apart during DNA replication?

It’s important so that replication can take place at all. Helicase unwinds the DNA and allows DNA polymerase to replicate a strand of DNA. The H bonds between the bases of the strands must break for this to happen. If they didn’t break apart, there would be no way for DNA polymerase to fit the strand to make a new, complementary one.
