Mitosis Phases
Phases of Mitosis
| Question | Answer |
|---|---|
| What are the three stages of interphase | G1, S, G2 |
| What happens in G1 | cell growth, duplication of cytoplasm and organelles, centrioles are copied |
| What happens in S | chromosomes of parent cells are making copies of themselves |
| What happens in G2 | last minute preparation is being made for nuclear division |
| What is interphase | cell metabolizes and prepares to divide |
| Describe prophase | division of duplicated chromosomes in the parent into two nuclei |
| Describe metaphase | chromosomes cluster at the center of the cell, centromeres align in the middle of the spindle |
| Describe anaphase | centromeres split, chromatids each have a chromosome, separated chromosomes are pulled to opposite ends of the cell as spindle microtubules shorten |
| Describe telophase | final phase, begins when chromosomes stop moving, chromosomes on each end begin to decondense and uncoil, forming chromatin/nuclear membrane forms around each chromotin mass, spindle breaks down and disappears |
| Describe cytokinesis | parent cells divide organelles and cytoplasm for two new cells |
