Answer :

Metaphase is the organization phase and anaphase is the separation phase.

A stage of cell division is called metaphase (mitosis or meiosis). Typically, each chromosome is dispersed throughout the cell nucleus. The nucleus of the cell disintegrates during metaphase, and the chromosomes gather and travel toward the Centre of the dividing cell. When studied under a microscope at this point, the chromosomes may be distinguished. In the laboratory procedure of karyotyping, defective chromosomes are found by using metaphase chromosomes.

Many years before we realized what that genetic material was, the ability to observe chromosomes under a microscope in metaphase allowed us to identify them as having the genetic material. Later research revealed that the genetic material in chromosomes contains information and is composed of proteins and DNA.
