⟩ Because of DNA replication, two DNA molecules come to existence. Why is not it correct to assert that two “new” DNA molecules are created? What is the name given to the process concerning that fact?
During replication each chain of the DNA molecule act pairing new nucleotides and after the process, two newly formed chains made with the union of these nucleotides appear. Then two DNA molecules are created, each with one chain from the original molecule and one newly chain formed by new nucleotides. Thus, it is not entirely correct to assert that the replication produces two new molecules of DNA. It is better to affirm that two new half-molecules are created.
For this phenomenon DNA, replication is called semi conservative replication.
