Transcript of The Mitosis Cycle

CYTOKINESIS
PROPHASE
Listed here are the 10 parts of the cell important to mitosis: Daughter cells, cell plate, nucleus, DNA, nuclear membrane, spindle fibers, centrioles, chromosomes, centromere, chromatid. These are used by the cell during mitosis.

TELOPHASE
Telophase is the fifth phase. During telophase, the chromatids are now on either side of the cell. A nuclear membrane begins to form around the chromatids (chromosomes). The chromosomes begin to unwind back into DNA. The cell begins to split in two, with both still connected. Mitosis is now complete, but there is one more step.
ANAPHASE
The next step is Anaphase. The spindle fibers that are attached to the chromosomes pull them apart, resulting in the chromatids being pulled apart to both sides of the cell.








METAPHASE
In Metaphase, the third phase, the chromosomes line up in the center, and are held together by spindle fibers coming from the two asters. The chromosomes have two distinct parts, the chromatids. These chromatids are each held by a spindle fiber.











INTERPHASE
In Interphase, the first phase, the cell copies all the DNA inside its nucleus. This is so it can be given to each individual cell. This is all before mitosis actually began.









WHAT IS MITOSIS?
Mitosis is a process that occurs in eukaryotic cells. It is a process where chromosomes condense and separate. Chromosomes are made from strands of DNA condensing.
Why Is Mitosis Important And What Phases Are There?
Mitosis is important for many reasons. First off, without it, you would not be able to create new cells, meaning you couldn't exist. In it, since you transfer half of a cell's chromosomes to each of the "daughter cells", your new cells have your DNA, making you "you".

There are 6 phases in mitosis. They are listed here: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. These phases show how the cell splits into two new ones.

The 10 Parts Of The Cell Important to Mitosis
Prophase is the second phase of mitosis. This is when mitosis truly starts. The DNA condenses into rod like structures inside the nucleus: Chromosomes. The nuclear membrane begins to dissolve, and the nucleolus starts disappearing. Asters begin forming on the poles of the cell.







Interphase
in an actual cell.
Cytokinesis is the last step. In cells without a cell wall, the cell membrane pinches between the two distinct cells, separating them into two new complete cells. The nucleus is now fully visible.
