In the majority of cells arrested after S phase but before anaphase, sister minichromosome molecules are not topologically interlocked with each other.
The role of DNA topology in holding sister chromatids together before anaphase was investigated by analyzing the structure of a small circular minichromosome in cell cycle (cdc) mutants of the yeast Saccharomyces cerevisiae.
The close temporal association of the [Ca2 +] i transient with the onset of anaphase suggests that calcium may have a signaling role in this event.
Prior studies by Kerr el al, showed that PP2ACdc55 played an essential role in controlling the timing of metaphase to anaphase during meiosis, in other words preventing cells from prematurely exiting meiosis.
Despite this hard work from dynein, in roughly one - quarter of the cells observed, the spindle was misaligned, even after the paired chromosomes were pulled to opposite sides of the cell in late anaphase.
In approximately 43 % of the dividing human cells Kiyomitsu observed, the middle of the mitotic spindle was properly centered at the beginning of anaphase.
Kiyomitsu's latest work focuses on the next step of mitosis, called anaphase, when the microtubules tear the paired chromosomes apart so that one copy of each chromosome ends up in each of the new daughter cells.
As seen in this merged fluorescent image (early anaphase marked with magenta; late anaphase marked with green), such cells correct this problem by adjusting their cell membranes relative to the spindle (right), instead of shifting their spindles within the cell.
