What is the Difference Between Centrosome and Centromere?
🆚 Go to Comparative Table 🆚The main difference between a centrosome and a centromere lies in their structure and function within the cell. Here are the key differences:
- Centrosome: A centrosome is a cylindrical organelle made up of microtubules, which play a crucial role in shaping the spindle apparatus during cell division. Centrosomes are found only in animal cells and help organize cell microtubules, regulating the cell division cycle. They also assist in the development of spindle fibers, which help segregate chromosomes during cell division.
- Centromere: A centromere is a small, highly constricted region of DNA found in the middle of a chromosome. Its primary function is to provide a location in the center of a chromosome for the binding of sister chromatids and the attachment of spindle fibers during mitosis. Centromeres are responsible for the movement of chromosomes during mitosis.
In summary, a centrosome is an organelle that organizes microtubules and regulates the cell division cycle, while a centromere is a DNA region on a chromosome that binds sister chromatids together and attaches to spindle fibers during cell division.

Comparative Table: Centrosome vs Centromere
Here is a table comparing the differences between centrosomes and centromeres:
Feature | Centrosome | Centromere |
---|---|---|
Function | Helps in the formation of spindle fibers during cell division. | Helps the chromosomes to be attached to the spindle fibers during cell division. |
Composition | Composed of RNA and protein. | Composed of DNA and protein. |
Location | Organelle found in animal cells, located near the nuclear envelope in the cytoplasm. | Region of a chromosome, found in all eukaryotic cells. |
Number | One centrosome in each cell, containing two centrioles arranged perpendicularly. | More than one centromere in each cell, equal to the number of chromosomes. |
