Interphase

Interphase

It is made up of three subphases :G1, S, G2. The main stages of the cell cycle are gap 1, synthesis, gap 2, and mitosis. Gap 1 is a cell growth and normal functions. DNA synthesis are copies of DNA. Gap 2 is an additional growth. Mitosis includes division of the cell nucleus (mitosis) and division of the cell cytoplasm (cytokinisis).

Mitoisis

Mitoisis

The cell cycle is a repeated pattern of growth, division, and normal function that occurs in the eukaryotic cells (plants and animals). This takes place where the DNA is = Nucleus.

Prophase

Prophase

It is characterized by four events. Chromatin condenses to become chromosomes. The nuclear membrane (envelope) disappears. Centrioles have separated and moved to the opposite sides of the cell. Spindle fibers form a bridge between the end of the cell.

Metaphase

Metaphase

Chromosomes line up across the center of the cell. Each chromosome attaches to a spindle fiber at its centromere.

Anaphase

Anaphase

Centromeres that the sister chromatids split.


Sister chromatids separate becoming individual chromosomes. Separated chromatids move to opposite sides of the cell.

Telophase

Telophase

Chromosomes (each consisting of a single


chromatid) begin to lose their rodlike


appearance. They are becoming chromatin again. A new nuclear envelope forms (nucleus) around the chromosomes at each side of the cell. Spindle fibers break down and dissolve. The cytokinesis begins.

Cytokinesis

Cytokinesis



It is the division of the cytoplasm into two


individual cells. The process of it differs somewhat in plant and animal cells. In animal cells the cell membrane pinches the cell into two early daughter cells. In plant cells a structure known as a cell plate forms widway between the two nucleus, which gradually develops into a


separating membrane.
