Mitosis (Late anaphase) Kinetochore microtubules shorten as the chromatid (chromosome) is pulled toward the pole Astral microtubule Shortening kinetochore microtubule Increasing separation Elongating polar of the spindle poles microtubule
Mitosis (Late anaphase)
Mitosis (Telophase) Nuclear envelope re-forms Polar microtubules Decondensing chromosomes without kinetochore microtubules Nuclear envelope re-forming

Meiosis >Basic Concepts Meiosis is a special division mode which occurs during the formation of germ cells of the sexual reproduction individuals. Homologous chromosomes refers to a pair of chromosome which have same formation and structure,one come from father and another come from mother Synapsis refers to the process in which two homologous chromosomes pairing. Tetrad refers to the combination which was composed by four chromatid of homologous chromosomes
