which is essential for DNA condensation. We have also argued that unlinking of the sister chromosomes during DNA replication is aided by removal of pre-catenanes that are forming directly at or just ...

During interphase, individual chromosomes are not visible ... In any case, as mitosis begins, a remarkable condensation process takes place, mediated in part by another member of the SMC family ...

During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists ...

Chromosomes begin to condense, taking on the form that they are usually depicted in: four arms connected at a point. Each chromosome is, at this time, actually two identical copies. Each copy is ...
