Mitosis-MetaphaseIn Metaphase, the spindle fibres pull the chromosomes into the middle of the cell. Mitosis-Late ProphaseIn late Prophase, the spindle fibres finish forming and attach their centromeres to the chromosomes. Spindle fibres, tiny tube-like structures, begin to appear as well as centrioles, organelles that organize the fibres. The nucleolus disappears and the nuclear membrane starts to break down. Mitosis-Early ProphaseDuring early Prophase, the chromosomes that were replicated during the ‘Replication’ stage coil up into an ‘X’ shape and become visible under a microscope. Interphase-Continued Growth & Preparation After the DNA replication, the cell keeps growing and making materials, such as protein, for the ‘daughter’ cells that will be formed after cytokinesis. The DNA is located in chromatin, which is contained in the nucleus. During this process the cell has two complete sets of DNA. Interphase-ReplicationDuring the replication stage, the DNA makes a replica (copy) of itself. Interphase-Growth and PreparationDuring this first stage of interphase, the cell’s size increases while it creates proteins and nutrients essential for survival.
