In what phase do chromosomes move to opposite poles?
In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
In which stage of mitosis do chromosomes move to the opposite ends of the cells along the spindle fibers?
During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. During telophase, the nuclear envelope begins to re-form around the divided chromatids.
What happens during anaphase II?
In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. … Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid.
What processes occur during G2 phase?
So, what happens in G2 of the cell cycle? The second growth phase starts to prepare the cells with newly replicated DNA for entry into the mitosis phase by putting in place the necessary organelles for mitosis. The cell cycle is a vital part of the continued persistence of all eukaryotes and prokaryotes.
What happens in G1 G2 and S phase?
Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
