Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.
What is Anaphase l

What is the purpose of cytokinesis?
What is To separate the cytoplasm and cell membrane.
400
Nuclear membrane form each of the two sets of chromosomes.The chromosomes begin to spread out and the spindle begins to break down.

400
What is a major event of anaphase?
Sister chromatids separate
500
A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
What is mitosis
500
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
