Which phase is described below? The chromosomes condense, Each is made of two sister chromatids,(looks) like an "X" Each sister is a clone, the closest of kin, And acentromere connects them like siamese twinsThe nucleolus disappears it melts away, as the cell takes a ribosomeproduction holiday, the centrosomes separate, start spindle formationfor separating chromatids and cell elongation.

Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. Draw a 2n=4 cell at G1 of interphase. Draw the same cell at the start of prophase. Draw the same cell at metaphase. Draw the cell(s) that result at the end of cytokinesis.
