What is the Difference Between Centromere and Centriole?
🆚 Go to Comparative Table 🆚The main difference between centromere and centriole lies in their function and location within the cell. Here are the key differences between the two:
Centromere:
- The centromere is a region within the chromosome that links sister chromatids or dyads during cell division.
- It serves as the primary location for the attachment of spindle fibers during mitosis.
- Centromeres occur in all eukaryotic cells and are responsible for the movement of chromosomes during mitosis.
Centriole:
- Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
- They are involved in the synthesis and organization of spindle fibers, which aid in cell division by helping in the formation of spindle fibers that segregate chromosomes during cell division.
- Centrioles also play an essential role in the creation of flagella and cilia and assist in maintaining cell shape.
In summary, the centromere is a region within the chromosome responsible for linking sister chromatids and attaching spindle fibers during cell division, while centrioles are barrel-shaped organelles located in the cytoplasm that aid in cell division by organizing spindle fibers and playing a role in the formation of flagella and cilia.

Comparative Table: Centromere vs Centriole
Here is a table comparing the differences between centromeres and centrioles:
Feature | Centromere | Centriole |
---|---|---|
Definition | The centromere is the central region of the chromosome, consisting of highly constricted DNA. | Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope. |
Function | Centromeres play a crucial role in the movement of chromosomes during cell division. | Centrioles help in the formation of spindle fibers, assisting in the segregation of chromosomes during cell division. |
Location | Centromeres are found in the middle of chromosomes. | Centrioles are found near the nuclear envelope in the cytoplasm of animal cells. |
Cell Type | Centromeres are present in all eukaryotic cells. | Centrioles are present in most eukaryotic cells, except in higher plants and most fungi. |
Structure | Centromeres are a confined region of DNA. | Centrioles are small cylindrical organelles made of tubulin protein. |
