The events shown below occur during different phases:
a. Centromere splits, chromatids separate and move to opposite poles, chromatids are now called chromosomes.
b. Chromosomes cluster at opposite poles, decondensation of chromosomes, reappearance of the nuclear membrane, golgi bodies, and the ER.
c. Chromosomal replication.
d. Kinetochores attach to spindle fibres and chromosomes are arranged at the equatorial plate.
e. Condensation of chromosomal materials.

Which of the following correctly identifies each of the phases described?

The correct option is A

Interphase	Prophase	Metaphase	Anaphase	Telophase
c	e	d	a	b

In interphase, the cell grows and the nuclear DNA is duplicated.

Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei.

Prophase, which is the first stage of mitosis, follows the S and $G_2$ phases of interphase. In the S and $G_2$ phases, the new DNA molecules formed are not distinctly formed as chromosomes. Prophase is marked by the initiation of the condensation of chromosomal material.

Metaphase is a stage in the cell cycle in which spindle fibres attach to the kinetochores of chromosomes. Metaphase is characterized by all the chromosomes coming to lie at the equator. One chromatid of each chromosome is connected through its kinetochore to the spindle fibre from one pole and its sister chromatid is connected through its kinetochore to the spindle fibre from the opposite pole.

Anaphase is the stage of mitosis after metaphase, in which replicated chromosomes are split and the newly copied chromosomes are moved to the opposite poles of the cell. Centromeres split and chromatids separate. Chromatids move to opposite poles.

Telophase is the final phase of karyokinesis or the division of the nucleus. Chromosomes cluster at opposite poles and their identities are lost as discrete elements. The nuclear envelope assembles around the chromosome clusters. The nucleolus, Golgi complex and the endoplasmic reticulum reform.
