Question

What is the difference between centromere, centrosome and centriole?

Answer 1

Centromeres:

Centromeres occur in all the eukaryotic cells and are accountable for the movement of chromosomes at the time of mitosis.

Centrosomes:

Centrosomes occur only in the cells of animals, where they organize the microtubules and monitor the cell cycle.

Centrioles:

The tube-like compositions found in animal cells, which help in cell division are the centrioles.

Centromere	Centriole	Centrosome
1. It is a very confined region of DNA found in the middle of the chromosome.	1. They are the barrel-shaped organelles, which are two in number found close to the nuclear envelope in the animal cells’ cytoplasm.	1. It is an organelle, which functions as the organizing center for all the microtubules.
2. The prime activity of centromere is to provide a location in the center of a chromosome for microtubule binding through kinetochores.	2. It assists in the development of spindle threads, which helps in segregating chromosomes at the time of cell division.	2. They play an essential function in the creation of flagella and cilia, and also assist in the preservation of cell configuration.
