What are the phases of mitosis? | Interphase, Prophase, Metaphase, Anaphase, telophase and cytokinesis |
What happens in the "Interphase" | This is the cell recognising that it needs to split, chromosomes appear as chromatin threads, dna replicates and by the end of interphase chromosomes will have split into chromatins. |
What happens in Prophase? | Preparation of splitting, nucleus breaks up and chromatids are ready to go. Protein spindles form. |
What happens in Metaphase? | Chromosomes beging migrating to the equator of the cell, and spindles attach to the centromere of each chromosome |
What happens in Anaphase? | Chromatids seperate and are pulled to the poles of the cell by spindles. |
What happens in telophase? | Chromatids reach poles and become chromosomes, a nuclear membrane is formed around each bundle of chromosomes, chromosomes uncoil reverting to chromatin thread. |
What happens in Cytokinesis | The finalisation - the splitting of the cytoplasm ect. |
What are chromosomes? | compact DNA in a cell. |
How do chromosomes duplicate? | They duplicate to form two chromatids, but they are still recognised as one single chromosome until they split. |
