During which phase of meiosis do the sister chromatids separate and head towards opposite poles of the cell anaphase 1 or 2?
During anaphase, sister chromatids are separated at the centromere and are pulled towards opposite poles of the cell by the mitotic spindle. During telophase, chromosomes arrive at opposite poles and unwind into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.
At what phase of meiosis there are two cells each with separated sister?
Anaphase II, where the centromeres are cleaved, allows the kinetochores to pull the sister chromatids apart.
|Question||At what phase of meiosis there are two cells, each with separated siter chromatids that have been moved to opposite spindle poles?|
Which stage of meiosis do sister chromatids line up at the equator?
During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
During which phase of meiosis do the sister chromatids separate quizlet?
Sister chromatids separate during anaphase II.
During which phase of meiosis do the sister chromatids separate and head towards opposite poles of the cell quizlet?
As anaphase II proceeds sister chromatids are separated and are pulled toward the pole to which they are attached.
What happens during metaphase 2 of meiosis?
During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.
What events occur during meiosis I and meiosis II?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
