Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.
In which phase do sister chromatids begin to move towards the poles?
Sister chromatids move towards opposite poles in anaphase II of second division.
During which stage of meiosis do the sister chromatids begin to move toward the poles quizlet?
Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. Notice that in anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
During which phase do the sister chromatids begin to separate and start moving toward opposite poles of the cell quizlet?
Metaphase occurs in the middle of mitosis, when the chromosomes line up in the middle of the cell. The sister chromatids separate and begin moving toward opposite poles of the cell during which phase of mitosis? Sister chromatids separate and start their migration toward opposite poles during anaphase.
What happens if both sister chromatids move to the same pole?
The first round of chromosome segregation (meiosis I) is unique in that sister chromatids move together to the same spindle pole while homologous chromosomes move apart from each other to the opposite poles. … This leads to the formation of chiasmata, which maintain homolog association until the onset of anaphase I.
What phase are daughter cells in as a result of mitosis?
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
What do 2 haploid daughter cells form?
Meiosis I results in two haploid (N) daughter cells, each with half the number of chromosomes as the original cell. The chromosomes (sister chromatids) line up in a similar way to the metaphase stage of mitosis along the equator. The sister chromatids separate and move toward opposite ends of the cell.
What is the correct order of these meiotic events?
The correct order of mitotic events which occur during meiosis is: Formation of synaptonemal complex, recombination, separation of homologous chromosomes, separation of sister chromatids.
What must happen in order for a cell to move to S phase from G1 quizlet?
21) What must happen in order for a cell to move to S phase from G1? a) It must divide. … You then observe the behavior of each nucleus residing in the combined cytoplasm of the two cells.
