Front 2

Mitosis

Back 2

the purpose of mitosis is cell division: making two cells out of one.

B. the DNA is replicated inter phase (doing the S phase). at the end of DNA replication, the cell contain 2 identical seats of DNA.

C. in mitosis

prophase

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. centro meres that join the sister chromatin split

2.sister chromatid separate becoming individual chromosomes

3. separated chromatid move to opposite sides of the cell

Front 6

Telophase

Back 6

the last phase of mitosis

1. chromosomes ( each consisting of a single chromatid) 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 of fiber breaks down and dissolve

4. Cytokineses begins

Front 7

Cytokinesis

Back 7

cytokineses in the division of the cytoplasm into two individuals cells.

the process of cytokineses differs some what in plant and animal cells

In animal cells the cell membrane pinches the cell into two nearly daughter cell.

in plant cells a structure known as a plate forms midway before the 2 nucleus, witch gradually develops into a separating membrane
