Nimitz class aircraft carrier design. The more recent Nimitz Class carriers (CVN72-CVN76) have a displacement of 102,000t when fully loaded. They have a length of 317m and beam of 40.8m.
Each of these daughter cells has to contain 23 chromosomes, half of the original 46. Again these steps must occur in this exact order or the resulting cells will have an incorrect number of chromosomes.  It has probably become obvious at this point that mitosis and meiosis are not simple processes.
Best Answer: So that all newly produced cells have all the DNA of the original cell (except gametes of course). If DNA did not replicate (make exact copies) then new cells would not receive all the chromosomes and genes necessary for life processes. Each new cell would only have half the needed chromosome. If it could survive each successive generation of cells would have fewer chromosomes and of course after a few divisions cells would receive none at all.
