Monocentric chromosome

This section is about centromere number. For optical eyepiece, see Eyepiece § Monocentric.
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.

The monocentric chromosome is a chromosome that has only one centromere in a chromosome and forms a narrow constriction.

Monocentric centromeres are the most common structure on highly repetitive DNA in plants and animals.[1]
