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.
Cells â except for cancerous ones â cannot reproduce forever. When aging cells stop dividing, they become âsenescent.â Scientists believe one factor that causes senescence is the length of a cellâs telomeres, or protective caps on the end of chromosomes. Every time chromosomes reproduce, telomeres get shorter. As telomeres dwindle, cell division stops altogether.
