DNA replication results in two DNA molecules,

each one with one new strand and one original strand

each one with two original strands

one with two new strands and the other with two original strands

Where does the DNA molecule unzip at during DNA replication?

Between the sugar and phosphate

At what point in the cell cycle does DNA replication occur and why?

before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions

before a cell divides, to ensure that the DNA will fit into the resulting cells

during cell division, to ensure that the DNA will fit into the resulting cells

after a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
