Cell Cycle

Front 1

Interphase

Back 1

Interphase is made up of three substances: G1, S, and G2. The main stages of the cell are gap 1, sythesis, gap 2, and mitosis. Gap 1 is cell growth and normal functions. DNA sythesis copies DNA. Gap 2: additional growth. Mitosis includes cell division.

Mitosis

Back 2

The purpose is a cell division, making two cells out of one. The DNA is replicated in Interphase. At the end of DNA. The chromosomes have to break apart so that each new cell only has one set of chromosomes. Its divided into phases Prophase, Metaphase, Anaphase, and telophase.

Front 3

Prophase

Back 3

Chromatin condenses to become chromosomes. The nuclear membrane disappears. Centeriols have separated and moved to opposite sides of the cell. Spindle fibers.

Front 4

Metaphase

Back 4

1.Chromosomes line up across the center of the cell.

2.Each chromosome attaches to a spindle fiber at its centromere.

Front 5

Anaphase

Back 5

1.Centromerers that join the sister chromatids split.

2.Sister chromatids separate becoming individual chromosomes.

3.Seperated chromatids move to opposite sides of the cell.

Front 6

Telophase

Back 6

1.Chromosomes begin to lose their rodlike appearance. They are becoming chromatin again.

2.A new nuclear envelope forms (nucleus) around the chromosomes at each side of the cell.

3.Spindle fibers break down and dissolve. Cytokinesis begins.

Front 7

Cytokinesis

Back 7

The division of the cytoplasm into two individual cells. The process differs somewhat in plant and animal cells. In animal cells the cell membrane pinches the cell into new nearly daughter cells.
