Centromere vs. Chromomere: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 29, 2023
Centromere is the part of a chromosome that links sister chromatids, while chromomere is a bead-like structure on a chromosome.
Key Differences
A centromere is a constricted region of a chromosome that separates it into two sections, while a chromomere is a bead-like structure on a chromosome. The centromere is vital for the movement of chromosomes during cell division, whereas chromomeres play no role in this process. The structure of a centromere includes specific DNA sequences that are required for its function, unlike chromomeres. Centromeres are essential for the correct segregation of chromosomes, whereas chromomeres help to organize the chromosome. In conclusion, while both centromeres and chromomeres are components of chromosomes, they have different roles and structures.
The centromere is an important structure in a chromosome that ensures the accurate separation of chromatids during cell division. In contrast, chromomeres are bead-like structures that are part of the larger structure of a chromosome. The centromere contains specific DNA sequences that are essential for its function, unlike chromomeres. Furthermore, centromeres are necessary for the proper segregation of chromosomes, whereas chromomeres simply help to organize the chromosome. Therefore, while both centromeres and chromomeres are components of chromosomes, they have distinct functions and characteristics.
The centromere is a crucial structure in a chromosome, playing a vital role in the segregation of chromatids during cell division. In contrast, chromomeres are simply bead-like structures on a chromosome that help to organize it. The centromere contains specific DNA sequences that are necessary for its function, whereas chromomeres do not. Additionally, centromeres are essential for the correct segregation of chromosomes, while chromomeres are not.

Centromere and Chromomere Definitions
Centromere
A centromere is a region on a chromosome that links sister chromatids.
During cell division, the centromere ensures the chromatids separate correctly.
ADVERTISEMENT
Chromomere
A chromomere is a bead-like structure on a chromosome.
Chromomeres help organize the chromosome into a compact form.
Centromere
The centromere is involved in the movement of chromosomes.
The spindle fibers attach to the centromere to pull the chromatids apart.
Chromomere
Chromomeres are visible under a microscope.
They appear as darker areas on the chromosome.
Centromere
Centromeres contain specific DNA sequences.
These DNA sequences are necessary for the centromere's function.
Chromomere
Chromomeres are involved in the folding of chromosomes.
This folding helps the chromosome fit inside the cell nucleus.
Centromere
Centromeres are necessary for proper chromosome segregation.
If the centromere is not functioning properly, the chromatids may not separate correctly.
Chromomere
Chromomeres are not involved in chromosome movement.
They play a role in organizing the chromosome but not in its movement during cell division.
Centromere
Centromeres are essential for cell survival.
Without proper centromere function, the cell may not survive.
Chromomere
Chromomeres are found along the length of a chromosome.
Each chromomere contains a specific part of the chromosome's DNA.
Chromomere
One of the serially aligned beadlike granules of concentrated chromatin that constitutes a chromosome during the early phases of cell division.
Chromomere
(genetics) Any of a group of beadlike granules of chromatin that constitutes a chromosome during cell division.
