Two identical DNA molecules result from the replication process, with one original strand and one new strand. This process is called semi-conservative replication. It is important to understand that semi-conservative replication is a complex, enzyme-controlled reaction. To understand just how complex DNA replication can be, it must be stated that deoxyribose is a five-carbon sugar. Chemists number the carbon atoms, 1 to 5.
The gaps are closed with the action of DNA Polymerase (adds complementary nucleotides to the gaps) and DNA Ligase (adds phosphate in the remaining gaps of the phosphate - sugar backbone). Each new double helix is consisted of one old and one new chain. This is what we call semiconservative replication.
