Given a list of steps and an additional step, determine where the step fits into the original list of steps. A correct answer, correctly places the given step into the set of steps so that it creates a new plausible set of steps. Output must be formatted as 'After step n', where n is the step number after which the given additional step is to be inserted.

Q: Steps: (1) In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell (2) In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell (3) In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere (4) In anaphase the sister chromatids separate into individual chromosomes and are pulled apart (5) During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes (6) Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
