]The life cycle of a eukaryotic cell is a complex and ongoing process that typically occurs in three primary stages known as Interphase, Mitosis and Cytokinesis. We begin with Interphase, which in itself includes three smaller aspects referred to as G1, S and G2. G1 begins with the new cell creating necessary materials for the succeeding stages. The S stage is responsible for the replication of deoxyribonucleic acid (DNA), the genetic material of the cell. In the S stage, the DNA has progressed into long, thin strands known as chromatin. When each strand as been completely replicated it is connected to a compatible centromere. G2 stage has now begun and specialized enzymes are used to check the strands of DNA for possible errors. After the strands are checked, proteins for the succeeding stage of Mitosis are synthesized.

Mitosis is now finished, it has caused the replication and division of the nucleus, but now the cell must fully divide.

Metaphase consists of the pieces of spindle attaching themselves to the chromatids. The spindle moves the chromatids so that they create an equatorical plane of the cell around the edges of the cell, where the narrower sides of the spindle occur. The chromatids are then "back to back" so to speak, each facing a different side of the cell. Anaphase will then begin as the centromeres divide the identical chromatids into singular chromosomes, which are set on a path down the fibers of the spindle to opposite sides of the cell.

Telophase begins when all the chromosomes have moved to their reserved sides of the cell. A new membrane then forms, surrounding the newly created chromosomes. The spindle structure will then break apart and the chromosomes will begin to unwind within themselves. The chromosomes are now referred to as chromatin and are so small that they cannot be viewed from a light microscope. The chromatin can only be seen by an electron microscope because the chromatins are extremely thin strands of DNA.
