During which phase do the sister chromatids begin to separate and start moving toward opposite poles of the cell quizlet?

Sister chromatids separate and start their migration toward opposite poles during anaphase.

During which phase do the sister chromatids begin to separate and start moving toward opposite poles of the cell?

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.

During which phase of meiosis do sister chromatids separate and move toward opposite poles of the cell being pulled by microtubules?

During anaphase II sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles.

During which phase of mitosis do sister chromatids separate to opposite poles of the cell group of answer choices?

During mitosis, sister chromatids separate from each other during anaphase.

During what phase of mitosis would the sister chromatids are separated and pulled to opposite poles of the cell by the spindle apparatus during a process called disjunction?

D Anaphase A. Anaphase A is the dynamic mitotic stage during which the sister chromatids separate further and migrate along the spindle to opposite spindle poles (Inoué and Ritter, 1975).

What is interphase G2?

G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2.

What is metaphase in mitosis?

Metaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.

During which phase of mitosis do sister chromatids separate?

Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

What happens during metaphase II?

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. … Cytokinesis follows, dividing the cytoplasm of the two cells.

Do sister chromatids separate in mitosis or meiosis?

The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis. Compare sister chromatids to homologous chromosomes, which are the two different copies of a chromosome that diploid organisms (like humans) inherit, one from each parent.

What happens during the 4 phases of mitosis?

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …

What phase is metaphase?

Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

What happens during the stages of mitosis?

What happens during mitosis? During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
