The two strands of nucleotides in a DNA molecule need to be separated during Polymerase Chain Reaction (PCR) for several reasons:

1. Denaturation: The first step in PCR is denaturation. This is where the double-stranded DNA molecule is heated to break the hydrogen bonds between the base pairs. This separation results in two single strands of DNA.

2. Annealing: The next step is annealing. Here, short pieces of DNA called primers attach themselves to each of the single strands. The primers are designed to bind at the start and end of the section of DNA to be copied. However, they can only bind if the two strands of the DNA molecule have been separated.

3. Extension: The final step is extension. Here, an enzyme called DNA polymerase attaches itself to the primers and adds nucleotides to extend the sequence. This can only occur if the DNA strands are separated, as the enzyme needs to be able to read the sequence of nucleotides on the single strand in order to create a complementary strand.

In summary, the two strands of nucleotides in a DNA molecule need to be separated during PCR to allow the primers and DNA polymerase to bind and create new copies of the desired DNA sequence.
