Interphase |
It is made up of three subhases : G 1, G 2,S 2. mitosis and cytokinesis 3.the main stages of the cell cycle are gap 1 ,synthesis , Gap 2, and mitosis Gap 1: cell growth and normal function DNA synthesis: copies DNA Gap 2: additional growth Mitosis: includes divison of the cell nucleus (mitosis) and divison of the cell cytoplasm ( cytokinesis ) |
|
Mitosis |
A. The purpose of it is cell divison making two cells out of one B. The DNA is replicated in interphase (during the sphase). At the end of the DNA replication, the cell contains two identical sets of DNA c. In mitosis, the chromosome have to break apart so that each new cell only has one set of chromosomes. D. Mitosis is divided into four phases: prophase, metaphase, anaphase, and telophase |
|
Prophase |
It is a characterized by four events 1. Chromosome condeness to become chromosome 2. The nuclear membrane (envelope) disappears 3. Centroiles have separated and moved to opposite sides of the cell 4.Spindle fiber form a bridge between the end of the cell |
|
Metaphase |
It is a chromosome line up across the center of the cell 2. Each chromosome attaches to a spindle fiber its centromere |
|
Anaphase |
1.It is a centromere that join the sister chromatids split 2. Sister chromatid separate becoming individual chromosome 3.Separate chromatids move to opposite sides of the cell |
|
Telophase |
1. it is a chromosome (each consisting of a single chromatid) begin to lose their rodlike appearance. They are becoming chromatin again 2.A new envelope form (nucleus) around the chromosome at each side of the cell 3.spindle fiber break down and dissolve |
|
Cytokinesis |
It is the divison of the cytoplasm into two indivdauls cells The processof cytokinesis differ somewhat in plants and animals cells the membrane pinches the cell into two nearly daughter cells In plant cells a structure know as a cell plate forms midway between the 2 nucleus which gradually develope into a separating membrane Cells divide at different rates |
