Name of protein is tubulin which is called spindle fibers when moving chromosomes .
The centromere
During mitosis, protein fibers attach to the chromosomes on opposite ends of the cell, then help to pull them apart so that the cell can divide into daughter cells with copies of all the chromosomes.
During mitosis the fibers of each individual chromosome are drawn together, forming the tightly packed chromosomes that you can see through a microscope.

A cell splits in two, with each half getting half of the chromosomes.
Centrosomes
Chromatin is intertwinted mass of fine thread-like structure made of DNA and protein. During cell division (mitosis and meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.
During mitosis and meiosis, kinetochores move chromosomes across the spindle fibers. The kinetochores serve as vehicles and the fibers serve as roads.
B chromosomes
Chromosomes are an organized structure of DNA and protein that is found in cells.

Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The Chromatin and Nucleosome are two of the most important parts.
