Explanation:
Detailed explanation-1: -During interphase, the chromosomes are decondensed and distributed throughout the nucleus, so the nucleus appears morphologically uniform. At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division.
Detailed explanation-2: -Answer and Explanation: It is important that the DNA is replicated before division because each of the daughter cells that are produced need to function independently once they are split. Further, DNA can only be produced with a template, so the replication must occur before division.
