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 ...

During prophase, the replicated pairs of chromosomes condense and compact themselves. The pairs of chromosomes that have been replicated are called sister chromatids, and they remain joined at a ...

Our studies on chromosome condensation and segregation utilize a combination of biochemical, cell biological, and molecular genetic approaches. J. T. P. Yeeles and K. J. Marians, Dynamics of ...

In meiotic prophase I, chromosome compaction is further complicated by the need to condense and restructure chromosomes in the context of a homologous partner. In several organisms both chromosome ...
