Answer:
...which are identical to the original parental DNA molecule.
Step-by-step explanation:
Before a cell will divide the DNA it contains must first replicate to ensure that the resulting cells from the division will contain the same DNA for it to function similarly as well. Replication of DNA is a semi-conservative because the resulting DNA molecule will be half old or half new, where one strand is from the parent DNA and the other is a newly formed strand.
The newly formed strand of each side will be identical to the former complementary strand before it unzipped.
