Telophase

Definition
noun
The final phase following anaphase of cell divisions (i.e. mitosis and减数分裂所反映出的),以及完整的年代eparation of the chromosomes
Supplement
Cell divisions ineukaryotes, particularly mitosis and减数分裂, are important since they give rise to newcells. Mitosis produces two cells that are genetically identical. Meiosis produces four cells that are genetically dissimilar and in which thechromosomes are reduced by half. Both mitosis and meiosis are comprised of chronological phases: (1)prophase, (2) metaphase, (3) anaphase, and (4)telophase. Since减数分裂is comprised of first and second meiotic divisions, these phases occur twice, each designated as I and II.
Telophase is the final phase that follows after anaphase, i.e. when thechromosomes separate and move towards the opposite. At telophase, the chromosomes continue to move until they are completely separated and two sets of nuclei are formed. During late telophase,cytokinesisbegins.
In减数分裂, telophase occurs twice, i.e. telophase I at first meiotic division and telophase II at second meiotic division.
