Task: Question Answering
Input (English): Process:  -Prophase is the first and longest stage of mitosis -In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere -In anaphase the sister chromatids separate into individual chromosomes and are pulled apart -During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes -Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
 Question: What is the effect of if during anaphase sister chromatids separate on helping mitosis to proceed normally.?
