Chromosomes reach the centrioles
WebCentrioles help organize cell division. Centrioles are not present in the centrosomes of other eukaryotic species, such as plants and most fungi. G 2 Phase (Second Gap) In the G2 phase, the cell replenishes its energy stores and synthesizes proteins necessary for chromosome manipulation. WebThe centrosomes/centrioles move to opposite poles of the cell. And just visible under a light microscope, the sister chromatids are coiled more tightly. Their movement is the important event during cell division. Figure 3. During prometaphase, mitotic spindle microtubules from opposite poles attach to each sister chromatid at the kinetochore.
Chromosomes reach the centrioles

WebThe centromeres are duplicated so that each chromatid becomes an independent chromosome and is attached to a spindle fiber connected to one of the two poles. The onset of anaphase is characterized by the movement of the chromosomes toward opposite poles of the spindle. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/the-cell-cycle/
