WebApr 28, 2017 · Centromere Definition. The centromere is the point on a chromosome where mitotic spindle fibers attach to pull sister chromatids apart during cell division. When a cell seeks to reproduce itself, it must first make a complete copy of each of its chromosomes, to ensure that their daughter cell receives a full complement of the parent …

WebCentromere, structure in a chromosome that holds together the two chromatids (the daughter strands of a replicated chromosome). The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored. The spindle is the structure.

WebA: Short arm (p arm) B: Centromere. C: Long arm (q arm) D: Sister Chromatids. In humans, centromere positions define the chromosomal karyotype, in which each chromosome has two arms, p (the shorter of the two) and q (the longer). The short arm 'p' is reportedly named for the French word "petit" meaning 'small'. [1] definition

WebBiology definition: A centromere is the dense and constricted region of a chromosome. It is where the sister chromatids attach after DNA replication and kinetochore assembly (for spindle fiber attachment) take place before mitosis. It contains highly specialized repetitive DNA sequences (e.g. satellite DNA) of a chromosome linking sister ...
