WebAnswer (1 of 3): Satellite chromosome Satellite chromosomes are chromosomes that contain secondary constructs that serve as identifying markers. Besides the centromere, one or more secondary constrictions can also be observed in some chromosomes at metaphase. WebDec 27, 2024 · Here, it is hypothesized that the chromatin filament in the loops and topologically associating domains is folded within the thin layers of the multilaminar chromosomes. It is also proposed that multilayer chromatin has two states: inactive when layers are stacked and active when layers are unstacked. Importantly, the well-defined …
