As the spindle fibers shorten or lengthen, the kinetochore generates the forces required to pull the sister chromatids apart. This differential regulation ensures that the sisters remain attached only at the centromere just before anaphase, creating the tension necessary for proper alignment on the metaphase plate.

These applications highlight how fundamental research into these cellular components translates directly into clinical diagnostics and therapeutic tools. These sisters are held together along their entire length by a protein complex known as cohesin, creating the characteristic X-shape visible during cell division.
The term applies to the duplicated chromosome until the moment the cohesin is cleaved, allowing the chromatids to separate and migrate to opposite poles of the cell. It functions as the molecular handle that motor proteins and spindle microtubets grab onto during cell division.

Furthermore, errors in meiosis, the division process that creates gametes, can lead to nondisjunction, causing conditions such as Down syndrome, where an extra copy of chromosome 21 is present. Within the intricate architecture of the eukaryotic cell, the faithful transmission of genetic material during division represents one of biology’s most precise operations.
