cohesin (plural cohesins)
(biochemistry) Any of a class of proteins responsible for binding the sister chromatids during mitosis
This is followed by anaphase II, in which the remaining centromeric cohesin is cleaved allowing the sister chromatids to segregate. Source: Internet
The protein complex cohesin holds sister chromatids together from the time of their replication until anaphase. Source: Internet
Unlike in mitosis, only the cohesin from the chromosome arms is degraded while the cohesin surrounding the centromere remains protected. Source: Internet
When cells enter mitosis, the sister chromatids (the two copies of each chromosomal DNA molecule resulting from DNA replication in chromatin form) are linked along their length by the action of the cohesin complex. Source: Internet
