WEBThe centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the chromatids. During mitosis, spindle fibers attach to the centromere via the kinetochore .

WEBThe centromere is a specialized site on a chromosome that directs the segregation of chromosomes to daughter cells during cell division (mitosis). The goal of mitosis is to divide and partition the genome equally by distributing one copy of each chromosome to the nucleus of each daughter cell and centromeres play a key role in this process.
