During anaphase, each pair of chromosomes is separated into two identical, … WebJul 17, 2024 · In anaphase I of meiosis, the following events occur: Chromosomes move to the opposite cell poles. Similar to mitosis, microtubules such as the kinetochore fibers interact to pull the chromosomes to the cell poles. Unlike in mitosis, sister chromatids remain together after the homologous chromosomes move to opposite poles.
WebNov 20, 2024 · Anaphase. In anaphase, chromosomes are split to opposite poles of the cell. In anaphase of meiosis I cohesin at the centromeres of the chromosomes is not cleaved … WebDuring anaphase, the sister chromatids separate and move to opposite ends of the cell. Lastly, during telophase, a nuclear envelope forms around each set of chromosomes, and …
WebOct 29, 2015 · The next phase is anaphase, during which one chromatid from each pair moves to opposite poles of the cell. At this point the chromatids are now individual chromosomes, and there are now two identical sets of chromosomes. During telophase and cytokinesis, the cell divides into two cells, each with identical sets of chromosomes. … WebApr 25, 2024 · The mitosis process undergoes five steps: prophase, prometaphase, metaphase, anaphase and telophase. These steps are defined by chromosomes condensing, temporary removal of the nuclear membrane, separation and movement of separated chromosomes to opposite ends of the cell by spindle fibers.
