What structures become pulled apart during anaphase?
During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell (Figure 3c). At this point, each chromatid is considered a separate chromosome.
What is separating during anaphase?
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.
What is being pulled apart in anaphase 1?
Anaphase I: In anaphase I, the attachment of the spindle fibers is complete. The homologous chromosomes are pulled apart and move towards opposite ends of the cell. Do not confuse this with the pulling apart of sister chromatids! This is the point in which reduction occurs with 23 chromosomes moving to each pole.
What pulls apart during anaphase and how does this occur?
Explanation: Separation of the sister chromatids by the microtubules pulling them to opposite poles occurs in anaphase.
In which phase are chromatids pulled apart?
Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin — which linked the sister chromatids together during prophase — causes this separation to occur.
What is being separated during anaphase of mitosis quizlet?
Anaphase is characterized by the separation of sister chromatids.
What is separated in anaphase II?
Anaphase II involves separation of the sister chromatids. Anaphase II involves separation of the sister chromatids.
What are chromosomes pulled apart by?
Almost immediately after the metaphase chromosomes are aligned at the metaphase plate, the two chromatids from each chromosome are pulled apart by the mitotic apparatus and migrate to the opposite spindle poles in a process known as anaphase.
What pulls the sister chromatids apart in mitosis?
The movement of chromosomes is facilitated by a structure called the mitotic spindle, which consists of microtubules and associated proteins. Spindles extend from centrioles on each of the two sides (or poles) of the cell, attach to the chromosomes and align them, and pull the sister chromatids apart.
