Analyse the events during every stage of cell cycle and notice how the following two parameters change? (i) Number of chromosomes (n) per cell . (ii) Amount of DNA content (C) per cell.  

Answer:

(i) The number of chromosomes (n) is double in the prophase, metaphase and anaphase stage of an organism. In the telophase stage, during daughter cell formation, the number of chromosomes get reduced to half. (ii) Amount of DNA content (C) per cell also changes during different phases of cell division. It is double in the prophase, metaphase and anaphase stage of an organism. In the telophase stage, during daughter cell formation, the number of chromosomes get reduced to half than that of their parents.
