Rec8 joins the whole length of the sister chromatids together, and, as meiosis proceeds, is lost in a stepwise manner that correlates with the loss of sister-chromatid cohesion. Figure 1 ...

Meiosis is the generation of germ cells (eggs and sperm). In meiosis, DNA replication is followed by two division cycles: meiosis I, which segregates homologous chromosomes and meiosis II, which ...
