WebMay 5, 2024 · In fact, the reproducibly observed trefoil knot in modeling studies based on single-cell Hi-C data was spread over 25 segments, which corresponds to a 2.5-Mb large chromatin portion (25, 28). To probe the knottedness of chromatin at a smaller scale than these probed using the single-cell Hi-C approach, one would need a method that can … Webvortex filament of strength K having the shape C in figure 2 (the trefoil knot), then K, = fcu.dl = fC1 u.dl+f u.dl = 2K.
