kohesinens
Kohesinens is a biological term referring to the protein complex responsible for holding sister chromatids together after DNA replication during cell division. This complex plays a crucial role in ensuring that each daughter cell receives a complete and accurate set of chromosomes. The cohesin complex is composed of several protein subunits, including SMC1, SMC3, SCC1 (also known as RAD21), and SCC3 (also known as STAG). These proteins assemble into a ring-like structure that encircles the two sister chromatids.
The loading of cohesin onto chromosomes occurs during the S phase of the cell cycle, coincident with
