Each sister chromatid of a chromosome is
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 copy of the chromosome is referred to as a sister chromatid and is physically bound to the other copy.(Note that the term "sister chromatid" is used regardless of the sex of …
