The two new strands are different from each other ,both of them have only one strand from the original DNA and the other strand is complementary . eg if a strand has the following base pairs .. AACCGGT ( consider this as the strands)
TTGGCCA
now they are going to be seperated AACCGGT TTGGCCA
TTGGCCT AACCGGT
as u can see the two NEW strands formed are similar but NOT IDENTICAL to each other .
