Verified By Collegedunia

The Correct Option is D

Solution and Explanation

During late prophase, specialised structures called kinetochores develop on either surface of the centromere. Chromosomal fibres get attached to kinetochore. Chromomeres are beaded structures on the chromosomes which are found particularly at the prophase-I (particularly at leptotene) of meiosis-I. Chromocentre is developed due to the fusion of centromeric regions of all the chromosomes of a cell. Centrosome is found in animal cells (absent in plant cells). It is found near the nucleus. Each centrosome is made up of two centrioles and each centriole is a cylindrical structure with a diameter of $1,500-1,800$ A and is made up of nine fibrils.

Mitosis

Mitosis is a cell division stage of the cell cycle during which DNA in the nucleus cell gets split into two equal chromosome sets. Cell division results in the formation of genetically identical cells with the same number of chromosomes. Mitosis is also known as equational division.

Features of Mitosis:

In each cycle of cell division, two daughter cells are formed from the parent cell.
The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.
In plants, mitosis leads to the growth of vegetative parts of the plant like root tip, stem tip, etc.
Segregation and combination do not occur in this process.

Stages of Mitosis are:

Interphase: Technically, it is not a part of mitosis, however, it is still a crucial process as it leads up to the process of mitosis. Hence, the interphase refers to all the other stages of cell cycle other than mitosis.
Prophase: It is the first stage of mitosis. It is also the longest phase of mitosis, where the chromatin condenses into chromosomes and the nuclear membrane breaks down (in prometaphase). In animal cells, the centrioles located near the nucleus begin to split and move to the opposite ends of the cell.
Metaphase: In this phase, the microtubules pull on the chromosomes with equal force, and the chromosome moves to the center of the cell.
Anaphase: This phase is marked by the splitting of the sister chromatids. These sister chromatids then become the chromosomes of the daughter nuclei.
Telophase: It is the final phase of mitosis. It begins after the replicated, paired chromosomes are separated and pulled at the opposite ends of the pole.
