In contrast to cohesin, which binds two sister chromatids together, condensin is thought to bind a single chromatid at multiple spots, twisting the chromatin into a variety of coils and loops ...

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 ...

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 ...

Johnson's research interests include genetic toxicology, sister chromatid exchange, and behavioral responses in animals to hormonal and chemical stimuli. Johnson's research interests include genetic ...
