Centromere vs. Chromomere
Main DifferenceThe main difference between Centromere and Chromomere is that the centromere is the specialize DNA order of a chromosome that associates a pair of sister chromatids (a dyad) whereas Chromomere also known as an idiomere, is one of the successively align beads or granules of a eukaryotic chromosome, causing from local twisting of a constant DNA thread.

Difference Between Centromere and Chromomere
Centromere vs. Chromomere
Centromere denotes to a region of a chromosome to which the microtubules of the spindle assign, through the kinetochore, during cell division while chromomere denotes to one of the small bead-shape and heavily staining masses of coil chromatin that contain a linear organization besides the chromosome.
Centromere vs. Chromomere
The centromere is the outcome of DNA replication, which arises in the interphase on the other hand chromomere is observable during the prophase of both mitosis and meiosis.
Centromere vs. Chromomere
Monocentric organisms hold a single centromere per chromosome, and holocentric organisms comprise more than one centromere per chromosome on the flip side a large number of chromomeres arise throughout the chromosome.
Centromere vs. Chromomere
Centromere arises in the middle of the chromosome or on the arm oppositely chromomeres appear beside the whole chromosome.
Centromere vs. Chromomere
The function of the centromere is to grip two sister chromatids together and deliver sites for the connection of spindle microtubules through kinetochore conversely chromomeric maps is to provide the precise location of genes on a chromosome.

Centromere vs. Chromomere
The centromere is the condense part of the chromosome, which links the two sister chromatids together whereas the chromomere is linearly organizing chromatin granules beside the length of the chromosomes. Centromere happens during the interphase of the cell cycle where the DNA replication takes place whereas chromomere is observable during the prophase of both mitosis and meiosis. The centromere is the outcome of DNA replication, which occurs in the interphase whereas chromomere is noticeable during the prophase of both mitosis and meiosis. Monocentric organisms comprise a single centromere per chromosome, and holocentric organisms contain more than one centromere per chromosome whereas a large number of chromomeres arise through the chromosome. Centromere appears in the middle of the chromosome or on an arm whereas chromomeres occur along the whole chromosome. The function of the centromere is to grip two sister chromatids together and deliver sites for the attachment of spindle microtubules through kinetochore whereas that of chromomeric maps is to provide the precise location of genes on a chromosome.
What is Centromere?
A centromere is the central area of a chromosome made up of highly condense DNA. The principal function of a centromere is to grip the two sister chromatids together. Sister chromatids make after DNA replication in the interphase. The relationship of two sister chromatids arises through a cohesion complex. Centromere also delivers sites for the attachment of spindle microtubules through kinetochores. Kinetochores are the protein complexes that bond centromere to the spindle microtubules. The two forms of centromeres are point centromeres and regional centromeres. Point centromeres are the sites to which spindle microtubules are attaches. On the other hand, provincial centromeres are the DNA arrangements that define the location of the spindle microtubule connection. Centromere distributes the chromosome into two arms as long arm or q arm and short arm or p arm. Base on the position of the centromere, we can identify several types of chromosomes. The types of chromosomes are the following as Metacentric chromosomes contain equal lengths in both p and q arms. Submetacentric chromosomes comprise p and q arms which are relatively unequal in lengths. Acrocentric chromosomes q arm is lengthier than the p arm. Telocentric chromosomes the centromere locating at the terminal end of the chromosome.
What is Chromomere?
Chromomere is a tight coil chromatin thread (chromonemata) present in a chromosome. It is also known as idiomere. A sequence of chromomeres arise in a chromosome, and they can observe under a microscope when staining with nuclear dyes. Chromomeres are visible during the prophase of the mitosis and meiosis. They are made up of contract DNA. 95% of the chromosome condenses, making chromomeres while the remaining 5% arises in between the chromomeres. The huge chromomeres form in plants is known as nodes. The conjugation of the homologous chromomeres of the replicating chromosomes forms huge polytene chromosomes. The outline of the disks of these chromosomes results from the loci of particular genes. The arrangement of the formation of chromomeres is irreplaceable to the chromosome. Therefore the size, shape, and number of chromomeres rely on the chromosome. Chromomeres are the efficient units of a chromosome in modern cytogenetics. So, the development of chromomeres is a fundamental mechanism of gene regulation.
ConclusionA centromere is an essential unit on the chromosome which helps in the connection of spindle microtubules during cell division. Chromomere is a tight coil chromatin thread (chromonemata) present in a chromosome. The main variance between centromere and chromomere is their structure and function.
