Stage 2C: mitosis anaphase

Chromatids separate and are pulled apart to opposite sides or poles of the cell by the spindle fibers that are attached to the Centromeres.

Stage 2B: mitosis metaphase

Chromosomes line up in the middle or equator of the cell

Stage 2a: Mitosis prophase

Mito begins. The nuclear membrane breaks apart and chromosomes appear Rod-like under a microscope. Centrioles moved to the opposite ends of the cell. Spindle fibers in between the centrioles attached to the centromeres.

Stage 3: cytokinesis

Now that my mitosis is complete the cytoplasm splits into two. In plant cells a cell plate which will become the new cell wall forms. Two identical cells form. After the steps each cell is complete and begins the cell cycle again.

What Is cell cycle?

The cell cycle is the life cycle of a cell. The cell cycle beings when a new cell is formed and ends when that cell divides to form new cells. The cell cycle consists of three phases: interphase, mitosis, and cytokinesis.

Stage 1

The cell spends most of his life in this phase. If the cell is getting ready to divide, it must first copy chromosomes, centrioles, and other cell materials. Chromosomes now consists of two matching chromatids joined by a centromere. It has 2 copies of everything.

Stage 2D: mitosis telophase

The nuclear membrane forms again around each of the two sets of chromosomes. The spindle fibers disappear in the chromosomes unwind. Mitosis is complete because two nuclei have been formed.

Results

This results in two daughter cells that are identical to the original parent cell. These cells are identical to each other and identical to the cells from which they were formed at the start of the cell cycle.
