input question: What is the missing first step of the following process: - 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.???
