these are the ( two, three ) stages of the cell cycle.

stage 1: DNA is spread out in long ( strings, lines. ) before it divides, it ( increases, decreases ) the amount of sub cellular structures, such as ( mitochondria, cell membrane ) and ribosomes. it then ( duplicates, destroys ) its DNA which is copied and forms ( "X", "o" ) shaped chromosomes.

stage two: ( mitosis, the actual splitting of the cell ). the chromosomes line up at the ( centre, sides ) of the cell, and cell fibres pull them apart. the two arms of the chromosome is put on either side of the cell membranes form around each set of chromosomes. these become the ( nuclei, parent ) of the new cells - the nucleus has divided. lastly, the ( cytoplasm, ribosomes ) and ( cell membrane, nucleus ) divide.

the cell has now produced two daughter cells.
