Introduction

In cell biology there are similar terms but they have different functions. One of these cases are the centrosome and the centromere. Although they can be confused, in this article we will explain their difference.

What is the centrosome?

The centrosome is a Cell structure present in all eukaryotic cells that is responsible for the organization and separation of the filaments of cell division. It is made up of two centrioles that are found in a lighter, more spherical area of ​​the cell called the cytoplasm. The centrosome is necessary for the development of cilia and flagella, cell motility, cell division, change of cell shape and associates with microtubules.

Centrosome functions

• Organizes microtubules in the cell
• Helps in the formation and separation of cell division filaments
• Participates in the development of cilia and flagella
• It is involved in cell movement and shape change.

What is the centromere?

The centromere is the region on the chromosome where two chromatids join and is the site where the kinetochore is located, a protein structure that is responsible for the attachment of microtubules during mitosis. The centromere is found in a specific and constant position on each chromosome.

Centromere functions

• Holds the two chromatids together
• It is the site where the kinetochore is located and links with microtubules during mitosis
• Ensures the correct distribution of chromosomes in daughter cells during cell division

Conclusion

In summary, the centrosome and the centromere are different structures although they are related to each other. The centrosome is the place where the filaments are organized and divided during cell division, while the centromere is the site of union of the two chromatids and is related to the correct distribution of daughter chromosomes during cell division.
