Interphase |
Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During this phase, the cell copies its DNA in preparation for mitosis.
|
|
Mitosis |
A. The purpose of mitosis is cell division making two cells out of one B. The DNA is replicated in Interphase (during the s phase). At the end of DNA replication, the cell contains 2 identical sets of DNA. |
|
Prophase |
the first stage of mitosis or meiosis in eukaryotic celldivision, during which the nuclear envelope breaks down and strands ofchromatin form into chromosomes. |
|
Metaphase |
1. Chromosomes line up across the center of the cell 2. Each chromosome attaches to a spindle fiber at its centromere |
|
Anaphase |
1. Centromeres that join the sister chrmatids split 2. Sister chromatids seperate becoming indvuidual chromosomes 3. Seperated chromatids move to opposite sides of the cell. |
|
Telophase |
1. Chromosomes each consisting of a single chromatid begin to lose their rod like appearances. They are becoming chromatin again. 2. A new nuclear envolope forms nucleus around at each side of the cell. 3. Spindle fibers break down and disolve 4. cytokinesis begins |
|
Cytokinesis |
Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells. |
