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.
