What is it called when the chromosomes move to the poles?
Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. … More specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles.
What is the stage in which chromosomes reach the poles of the cells and Decondense nuclear envelope re forms at each pole and spindle apparatus disintegrates?
Telophase is the final stage of mitosis. During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end. As the nuclear envelope re-forms by associating with the chromosomes, two nuclei are created in the one cell.
What happens to the cell when it is in the telophase stage?
During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. … Along with telophase, the cell undergoes a process called cytokinesis that divides the cytoplasm of the parental cell into two daughter cells.
What happens during metaphase stage?
During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

What are the 4 stages of the cell cycle?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
What is S phase in cell cycle?
S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end.
