    The heating of a solution containing DNA leads to the unwinding of the double-stranded DNA. This happens when the Hydrogen bonds holding the two strands together become weak and break. This process of the separation of the double-stranded DNA into individual strands is called DNA melting or DNA denaturation.

    The modern tool of polymerase chain reaction or the PCR machine uses this process to separate the strands to enable the replication of DNA.
