Towards the end of metaphase, the metaphase checkpoint ensures that the mitotic spindle has been properly formed and the chromosomes are properly aligned at the metaphase plate. If the cell passes this checkpoint, then the anaphase-promoting complex signals the cell to proceed to the next step of...
This diagram outlines all stages of meiosis. During meiosis, cells perform two cell divisions: meiosis I and meiosis II. Each cell division can be broken up into P.M.A.T. phases, i.e., prophase, metaphase, anaphase, and telophase. However, the P.M.A.T phases within meiosis I and me...

Anaphase In anaphase, the paired chromatids separate at the kinetochores by which they were previously tethered and randomly segregate and move to opposite poles of the cell. The migration of the chromatids (now designated chromosomes) results from a combination of kinetochore movement along the spin...

Describe the events that occur in the four phases of mitosis (prophase, metaphase, anaphase and telophase). Why are proteins on the surface of cells so important and what roles do these proteins play? What is an ECG? What is its function? (a) Define acinar cells. (b) What is its func...
Phase 3 is anaphase B, during which the length of pole-to-pole spindles elongates. In the present study, we have addressed how phase 2 is coordinated at the molecular level in fission yeast. We have characterized the mitotic roles of Kin I homologs (Klp5 and Klp6) and have shown that ...
a. anaphase b. telophase c. prophase d. metaphase Chromosomes and Mitosis: Chromosomes form when a cell enters mitosis. In addition, each stage of mitosis is characterized by changes in the location of the chromosomes within the cell. Answer and...
6A Mock, 41 min; Supplementary Movie 12) and segregated properly in anaphase (Fig. 6A Mock, 48 min). In Hec1-depleted cells, prometaphase rosettes were formed (Fig. 6A siHec1, 13 min; Supplementary Movie 13) as shown before. Chromosomes were then partially assembled to the spindle...
