WebSMC proteins play important roles in chromosome mechanics other than condensation, including sister chromatid cohesion and recombination-mediated repair (Cobbe and Heck 2000). To carry out these different functions, the four classes of eukaryotic SMC proteins associate with each other in heterodimeric pairs. WebEach of the two copies of a chromosome are designated as a sister chromatid and they are physically linked together at a point on the chromosome called the centromere. Once the chromosomes move to …
