Document Summary

Theme 4: module 1 and 2 review lecture. I prefer partying at the club - interphase, prophase, propmetaphase, Interphase: g0, g1, g2, s phase , m phase. Significance of mitosis reproduction of cells and replacement of tissues. Give scenario about a stage of cell division, compare and contrast. Nuclear envelope breaks down, does not get destroyed. Two types of microtubules: kinetochores, and non-kinetochore microtubules. Metaphase: look for chromosomes lined along metaphase plate. Chromatids will separate into individual chromosomes they are pulled to either side of the cell. Plant cell creates cell plate, and that is how it separates. Cyclin proteins and the cell cycle cyclin is the initiator of mitosis. Levels of cyclin fluctuate during different times of the cell cycle. Cyclin and cdk bind creating the c-cdk complex. Cdk cyclin dependent kinase - so it relies on the binding to. Cdk-c is also a mitotic promoting factor. When cyclin is no longer needed, it degrades.
