The separation of the sister chromatids marks the beginning of what structure?
The separation of sister chromatids marks the beginning of anaphase in mitosis or meiosis. During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
Which stage of meiosis do centromeres separate?
anaphase **Remember anaphase means apart
In animal cell xhich structure is thougth to produce the spindle fibres that help separate the sister chromatids during anaphase?
Centerioles
Is anaphaselor1 or anaphase 2 in meiosis more analogous to anaphase in mitosis?
Anaphase I of meiosis is more analogous to anaphase in mitosis than anaphase II. In anaphase I, homologous chromosomes are separated and pulled to opposite poles, similar to how sister chromatids are separated during mitotic anaphase. In contrast, anaphase II involves the separation of sister chromatids, which is akin to what occurs in mitosis but happens after a reductional division in meiosis. Thus, the mechanisms and outcomes of anaphase I align more closely with those of mitosis.
What phase kinetochores are motionless in relation to poles of cell?
During metaphase, kinetochores are motionless in relation to the poles of the cell. This helps ensure proper alignment of chromosomes along the metaphase plate in preparation for their separation during anaphase.
What is the structure responsible for the movement of chromosomes during anaphase?
the spindle fibers i think

What fibrous cellular structure disappears from the screen just as the cell leaves anaphase and progresses into telophase?
spindle
Which stage of meiosis do centromeres separate?

What specific stage in meiosis do homologous chromosomes separate?
Anaphase lAnaphase I
Do centromeres divide at anaphase you or II?
anaphase 2
Which phase of mitosis involves splitting or pulling apart the chromatids?

Does cytokinesis occur during anaphase?
No, it occurs after telophase, which is after anaphase.
What is an anaphase-promoting complex?
An anaphase-promoting complex is a complex of several proteins which is activated during mitosis to initiate the anaphase.
