Cohesion genetics

Sister chromatid cohesion refers to the process by which sister chromatids are paired and held together during certain phases of the cell cycle. Establishment of sister chromatid cohesion is the process by which chromatin-associated cohesin protein becomes competent to physically bind together the sister chromatids. In general, cohesion is established during S phase as DNA is replicated, and is lost when chromosomes segregate during mitosis and meiosis. Some studies h… WebMar 22, 2024 · A genetic disorder is a disease that is caused by an abnormality in the genome, or an organism’s complete set of DNA that includes all of its genes.
