Answer: It is important that a has a full set of DNA
Why is it important that the cell's DNA is duplicated before cell division?

Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full complement of chromosomes.

Thu Oct 25 2001 14:30:00 GMT-0400 (Eastern Daylight Time) · In cell biology mitosis (/ m aɪ ˈ t oʊ s ɪ s /) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. In general mitosis ( division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often ...

Thu Nov 11 2010 13:30:00 GMT-0500 (Eastern Standard Time) · During the S-phase of each cell cycle ( Figure 1 ) all of the DNA in a cell is duplicated in order to provide one copy to each of the daughter cells after the next cell division. The process of duplicating...
