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 ...

In general, the kinetochore position and the sister-chromatid cohesion site are spatially linked. Here, the authors find a meiosis-specific distal cohesion site decoupled from the kinetochore in ...

Since sister chromatids are identical to each other, recombination with a sister chromatid is expected, in most cases, to be a precise way for repairing DNA damage. Recombination between 2 different ...
