WebNational Center for Biotechnology Information WebChromosomes and chromatids also have different connections with other cells. Chromatids have the ability to fuse with other chromatids from other cells, creating a connection between these two chromosomes. This process, known as chromosome crossover, is an important tool for creating variation in the genetic material. 8. Chromatid …
WebSister 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 … WebThe sister chromatids are still tightly attached to each other by cohesin proteins. At this time, the chromosomes are maximally condensed. During anaphase, the “upward phase,” the cohesin proteins degrade, and the sister chromatids separate at the centromere. Each chromatid, now called a chromosome, is pulled rapidly toward the centrosome ...
