Monocentric chromosome

Monocentric centromeres are the most common structure on highly repetitive DNA in plants and animals.

In monocentric chromosomes there is one primary constriction and the centromere its CenH3 loci at this location.

[2] Holocentric chromosomes are found throughout the plant and animal kingdoms such as the nematode Caenorhabditis elegans.

[4] The centromere is the point of attachment for the mitotic apparatus[5] Deletions, duplications and translocations can produce a polycentric chromosome.

This is troublesome for cells that divide often since at the time of anaphase the polycentric chromosome does not move to opposite poles of spindle fiber and the cell dies.

Duplicated chromosome. (2) identifies the Monocentric centromere—the region that joins the two sister chromatids , or each half of the chromosome. In prophase of mitosis, specialized regions on centromeres called kinetochores attach chromosomes to spindle fibers.
